Strickland DNA Project BigY Update (16 February 2024)

New Strickland BigY results have arrived. The total number of BigY results for the Matthew/Thwaite Strickland family is now 24: 23 BigY results for Matthew Strickland Sr. descendants and 1 BigY result for Thwaite Strickland. The newest results are for a descendant of Matthew Strickland Jr > Jacob > Solomon (wife Amy Pace). We now have results through Solomon's son Hardy and also his son Ezekiel. With a second set of results through Solomon, we can place the Strickland family SNP R-FTB34984 as having occurred with either Jacob or Solomon. We need a descendant of Jacob who descends through a different son (not Solomon) to take a BigY test in order to determine whether Jacob or Solomon was the first Strickland to have this SNP. Family Tree DNA currently estimates SNP R-FTB34984 first occurred about 1704 CE (range 1505-1842 CE). Matthew Strickland Jr. did not have SNP R-FTB34984 since a descendant of his son Sampson did not have the SNP.

The Strickland BigY results chart below includes both the new results through Matthew Jr > Jacob > Solomon and the earlier results for the John Stricklin (c1730) participant who belongs to the R-BY122303 branch of the Matthew Strickland Sr family. His results became available in December 2023. (See the 20 December 2023 update.)

There are four Strickland BigY tests currently being processed by Family Tree DNA. Stay tuned. The project welcomes all Strickland (all spelling variations) from around the world to participate.

Strickland DNA Project BigY Update (20 December 2023)

BigY results for another Matthew Strickland descendant have arrived, bringing the total number of BigY results for Matthew's descendants to 22 and the combined Matthew-Thwaite Strickland branch of the Tree of Mankind to 23 BigY tests.

The new test results belong to the R-BY122303 branch of the Matthew Strickland family, viewed on the left side of the earlier results chart below (30 November 2023). The test taker is a descendant of John Strickland's son William Strickland who married Rhoda Speight in Wake County, NC in 1788. The family moved to Tennessee before going to Saline Co., Illinois, and then on to other locations. The R-BY122303 Strickland branch also includes Sampson County, NC, Stricklands. These two Strickland family branches share a more recent common Strickland ancestor. Which likely son or grandson of Matthew Sr. was the first Strickland man with R-BY122303? The Strickland DNA Project is looking for testing candidates from both Strickland family groups as well as descendants of Matthew Strickland Sr.'s son William Strickland (wife Oliffe).

Strickland DNA Project BigY Update (30 November 2023)

The Strickland DNA Project now has 309 members at FamilyTreeDNA, including autosomal Family Finder results and Y-DNA results (both STR marker results and BigY results). There are now 21 BigY tests for the Matthew Strickland Sr. family, 1 for Thwaite Strickland, and 1 for Peter Strickland. Another set of BigY test results are expected soon.
  
MATTHEW AND THWAITE STRICKLAND BIGY TEST RESULTS



R-BY195011 (NEW) - An Earlier Strickland Ancestor (unknown)
BigY results for a descendant of Thwaite Strickland became available in early 2023. His test results identified an earlier SNP, R-BY195011, representing an earlier ancestor shared by both Thwaite’s descendant and Matthew Strickland’s descendants. FamilyTreeDNA currently estimates the first man with SNP R-BY195011 was born about 1440 CE, within the range of years 1281-1568 CE at the 95% confidence interval (CI). Thwaite’s descendant does not share SNP R-BY99282 with Matthew’s descendants. Thwaite and Matthew’s descendants belong to two branches of the Y-DNA tree below R-BY195011. When additional Thwaite descendants take the BigY test, unique identifying SNPs for Thwaite’s family may be identified. Also, as others test, the time estimates for Matthew and Thwaite’s shared ancestor may become more refined.

R-BY99282 - Matthew Strickland, Sr. of Isle of Wight Co., VA
Matthew Strickland Sr.’s descendants are still identified by SNP R-BY99282. It is unknown whether Matthew Sr. was the first Strickland to be positive for SNP R-BY99282. All who currently belong to haplogroup R-BY99282 appear to be his descendants. FamilyTreeDNA currently estimates the birth of the first man with R-BY99282 at about 1552 CE and within the range 1413-1663 CE (95% CI).

Matthew Strickland Jr (wife Ann Braswell)
There are now two BigY test takers who are descendants of Matthew Strickland Jr who can identify their ancestry back to Matthew Jr. One is a descendant of Matthew Jr.’s son Jacob Strickland and the other is a descendant of Matthew Jr.'s son Sampson Strickland. The results for Jacob Strickland’s line became available in 2023 and are important results for the project. The big news for Matthew Jr.’s line is there is NOT a SNP associated with Matthew Jr. based on these two results.

Jacob Strickland’s line appears to have an identifying SNP, R-FTB34984 (NEW). This SNP is shared by Jacob’s descendant and a descendant of B. Bryson Strickland (b.1864 GA), suggesting the SNP likely occurred between Jacob’s birth about 1706 and before B. Bryson Strickland’s birth. FamilyTreeDNA currently estimates the SNP occurred with a man born about 1700 CE (range 1436-1847 CE, at the 95% CI), so possibly as early as Jacob Strickland. Testing other descendants of Jacob Strickland may help identify which Strickland man was the first to have the SNP. This SNP may help the B. Bryson Strickland descendant and others identify how they are likely connected to Jacob’s branch of the Strickland family, especially if the generation the SNP occurred can be identified.

Only one descendant of Sampson Strickland tested. It is not possible to know if there are any SNPs associated with his branch of the family until other descendants of Sampson take the BigY test.

It is surprising to have so few descendants of Matthew Strickland Jr. participate in BigY testing. Where are his descendants?

R-FTB7455 (Strickland identity unknown)
In 2023, three new BigY results belonging to Strickland haplogroup R-FTB7455 became available, for a total of nine people in the haplogroup. The shared ancestor associated with SNP R-FTB7455, a likely son or grandson of Matthew Strickland Sr., is unknown. FamilyTreeDNA estimates the first man with this SNP was born about 1650 CE within the range of years 1482-1756 CE at the 95% CI.

There are now five subbranches of the R-FTB7455 Strickland branch that can be identified by BigY results:
1) R-FTB8555 is associated with Frederick Strickland (b. 1741 NC) and his son Zachariah Strickland. Frederick lived in Wake County, North Carolina, and Abbeville District, South Carolina, before moving to Tennessee. A descendant of one of Frederick’s other sons is needed to test to determine whether Frederick had SNP R-FTB8555 or if his son Zachariah was the first to have the SNP.
2) R-FTC94313 includes Simeon Strickland (b. 1776 NC), and Irvin Strickland of Hall County, GA (b. 1780).
3) R-FTC94409 (NEW) includes Reuben Strickland (b.1794 Wake Co., NC). A test taker who is not in the Strickland DNA project now shares this SNP with the Reuben descendant. Reuben now belongs to a new, more recent haplogroup branch.
4) R-FTD50069 (NEW) includes William Strickland (b. 1773 SC) and a descendant of D. Loyd Strickland (b.1807 GA). William Strickland lived in Abbeville and Anderson Counties, South Carolina.
5) (NEW) A participant not in the project shares SNP R-FTB7455 with the other four groups, but does not have his own identifying SNP. By not sharing any of the other four SNPs, he creates a fifth branch of this line.

R-BY122303 (Strickland identity unknown)
No changes occurred in Strickland haplogroup R-BY122303 since the 2022 update. At least three Strickland family subbranches are identified by Y-DNA SNPs in this family branch. Few in this group have joined the Strickland DNA Project. See the November 2022 update below for details on this haplogroup and its descendant haplogroups.

The William H. Strickland (b.1811) line of Sampson County, North Carolina belongs to Haplogroup R-BY122303. None of the early documented Sampson County, North Carolina, Strickland lines have taken a BigY test. It would be good to have representation from the Sampson County, North Carolina Stricklands in the BigY testing.
       
OTHER STRICKLAND BIGY RESULTS
Only one Peter Strickland of New London, Connecticut participant has taken the BigY test. A second test is needed for comparison purposes. STR marker results show Peter Strickland belonged to a different Strickland family than Thwaite Strickland and Matthew Strickland. Perhaps a second Peter Strickland descendant will take a BigY test in the coming year.           

Strickland-related DNA test takers, please join the Strickland DNA Project!
The project welcomes all Stricklands and Strickland descendants to the project. If you are Strickland male just starting DNA testing, ordering a Y-DNA 37 marker test can be a good starting place. The project also accepts autosomal DNA test results.

If you are a Strickland-surname male, especially if you know HOW you are related to early Stricklands, please consider taking or upgrading to the BigY test. The BigY test includes the 111 Y-DNA markers as part of the BigY test, so part of the cost includes the 111 markers. Feel free to e-mail the project administrator to ask questions or discuss how a Y-DNA test might benefit you and the Strickland Family DNA Project. My e-mail is available by clicking on my name on the left under Administrators (with the envelope icon.)

Strickland DNA Project at Family Tree DNA now at 300 members! (16 January 2023)

On 12 January 2023, the Strickland DNA Project at Family Tree DNA reached 300 members. The project at Family Tree DNA includes Strickland-surnamed men who have taken Y-DNA tests and Strickland descendants, both men and women, who have taken autosomal DNA tests.

The Strickland DNA Project has included more than the current 300 participants at Family Tree DNA. Many of our early Strickland Y-DNA test takers, both in the pioneering special project at Brigham Young University and those who tested at Relative Genetics, are not included in the current 300 members. In 2007, there were 110 Y-DNA test takers in the Strickland DNA Project. Many did not transfer to Family Tree DNA; many of them are no longer with us. The early test takers laid the foundation for the project on which we are still building. These early test takers established the Matthew Strickland DNA signature (haplotype) and from them we learned that Matthew Strickland of Virginia and Thwaite Strickland of Connecticut were related. The project will ever be indebted to the foresight of Ron Strickland who established the Strickland DNA Project in late 2000. With the advancement in Y-DNA testing and the new tools coming available, we are coming to closer to accomplishing the vision of the early project members of using Y-DNA to place our Strickland ancestors on their branches of the Strickland tree using Y-DNA.

Stay tuned for some exciting news! We have some new BigY results available and Family Tree DNA has some new tools. We are waiting for Family Tree DNA to complete their analysis and then there will be an update.  


Strickland BigY Y-DNA Update (27 November 2022)

The BigY-700 test introduced in 2019 is a game-changer. The Y-DNA STR marker results (the 37-111 marker test results) can identify whether two or more men are related to each other but in most cases cannot tell us when the common ancestor lived.

The BigY-700 test identifies DNA changes called SNPs (pronounced "snip"). These SNPs are placed on a hierarchical SNP tree that shows how the SNPs are related to each other. Approximate time frames for when the SNPs occurred can be calculated. The BigY-700 test can identify family SNPs and family haplogroups in the genealogical time period. Combining SNP information with known lineages we can learn more about how related men, as identified by the STR markers, are related to each other and when their most recent common ancestor likely lived. (See the Frederick Strickland results below for the best example so far.)

Family Tree DNA's new Discover More tool for Y-DNA haplogroups includes a new Time Tree feature. Estimated time frames for common ancestors are updated when new results for a family branch of the haplogroup tree are completed. As more people test for a particular family line, the estimated time frames for the SNPs will become more refined.

The Matthew Strickland family Discover More Time Tree page can be viewed at the link below. Once on the Discover More Time Tree page you can then go to the Scientific Details page to view information about the predicted age of the SNP, the Haplogroup Story page, the connections pages, the Suggested Projects pages, and other informative pages about the Matthew Strickland family SNP. (Other haplogroups can also be viewed by updating the page with a different haplogroup.)
https://discover.familytreedna.com/y-dna/R-BY99282/tree

See an annotated Matthew Strickland family Time Tree chart below.

R-BY99282

There are currently 17 BigY-700 test results that are related to the Matthew Strickland of Isle of Wight Co., Virginia, family. All 17 test results share the ancestral SNP R-BY99282

The Scientific Details tool provides an estimate for the Time to the Most Recent Common Ancestor (TMRCA) of the first man with the "Matthew Strickland family haplogroup" R-BY99282. This ancestor's birth is currently predicted to be about 1565 CE and within a range of years between 1422 and 1678 CE with a 95% confidence interval (CI). This is earlier than Matthew's expected birth, suggesting Matthew may not have been the first Strickland to have the SNP, but all of the current test takers are believed to descendants of Matthew Strickland of Isle of Wight County.  A Thwaite Strickland descendant is needed to take or upgrade to a BigY-700 test to determine whether Thwaite Strickland descendants also share R-BY99282 with Matthew Strickland descendants or not. The BigY-700 test has the potential to help us determine how far back in time the common ancestor of Matthew Strickland and Thwaite Strickland lived. It should be noted that several of the current time estimates for the branching SNPs also appear to be earlier than suggested by known family information.

On the accompanying annotated Time Tree for the Matthew Strickland of Isle of Wight Co., Virginia, family below, the Time Tree shows the current Strickland family branches that have been identified with BigY-700 testing.
SNP R-BY99282 associated with the whole family group has a red icon. It is labeled "Matthew Strickland, IOW" although it appears earlier on the Time Tree than Matthew Strickland's birth.  

Currently, only one BigY-700 test taker with a known line back to Matthew Strickland of Isle of Wight County has tested. He is a descendant of Matthew Strickland Jr through his son Sampson and Sampson's son Abel. There currently isn't a branching SNP associated with Matthew Jr.'s family line. It is necessary to have two test takers who share the same branching family SNP for the SNP to be identified and added to the SNP tree.
Four other Strickland lines also currently do not share a branching SNP with any of the other test takers. These lines are the Eli Strickland line (1794), Henry Strickland (1805 GA) line, the Josiah Strickland line (1826 NC), and the Bryson Strickland line (1864 GA).

R-FTB7455

Six participants share the branching SNP R-FTB7455. The Strickland ancestor associated with R-FTB7455 is unknown. He is currently predicted to have been born about 1643 CE within a range of years between 1464 to 1774 CE (95% CI). The range of predicted years is wider than the documents suggest. It is likely that the common ancestor of this branch of Stricklands is one of the elder Matthew Strickland's sons or grandsons.

The R-FTB7455 Strickland's descendants include six participants:
a) Two descendants of R-FTB7455 share an interim ancestor identified with SNP R-FTC94313. The man first associated with R-FTC94313 is currently predicted to have been born about 1710 CE with a range of years between 1480 to 1862 (95% CI). Descendants of R-FTC94313 include participants from the Simeon Strickland (1776) line and the Irvin Strickland (1780) line.
 
b) Two descendants of R-FTB7455 are descendants of Frederick Strickland (1741 NC) through his son Zachariah Strickland (1770 NC). The Frederick>Zachariah participants share a branching SNP R-FTB8555. The man associated with R-FTB8555 is predicted to have been born about 1776 CE within a range of years between 1575 to 1905 CE (95% CI). The predicted birth year of 1776 and Zachariah's 1770 birth year are suggestive that the SNP may have occurred with Zachariah but Frederick is also within the range. It would be good to have a descendant of one of Frederick's other sons take the BigY-700 test to see if the SNP is only associated with the Zachariah branch or is ancestral to Frederick.

c) A descendant of Reuben Strickland (1796 NC) also is a descendant of the R-FTB7455 ancestor.
d) A person who has not joined the Strickland DNA Project is also a descendant of the R-FTB7455 ancestor.
These two participants currently do not share any branching SNPs below R-FTB7455 with anyone else that has currently taken a BigY-700 test.

R-BY122303

Six participants share SNP R-BY122303. The Strickland ancestor associated with R-BY122303 is unknown. He is currently predicted to have been born about 1653 CE within a range of years between 1483 and 1778 CE (95% CI). Again, this common ancestor may be a son or grandson of the elder Matthew Strickland.

The R-BY122303 Strickland descendants include:
a) James Strickland (1795 NC) line
b) William H Strickland (1811 NC) line
c) Two test takers who are not in the Strickland DNA Project who share SNP R-FT354025. The Strickland ancestor associated with R-FT354025 is currently predicted to have been born about 1677 CE within a range of years 1430 to 1841 CE (95% CI).
d) Two test takers who are not in the Strickland DNA Project who share SNP R-BY193790. The Strickland ancestor associated with R-BY193790 is currently predicted to have been born about 1762 CE within a range of years 1550 to 1897 CE (95% CI).

Strickland BigY Y-DNA Update (23 October 2022; rev. 28 November 2022)

-New BigY results have arrived. An update will be posted soon.
-A link to the new BigY Time Tree (and new Discover tool) has been added to the Links page

The Matthew Strickland family SNP tree starting with the SNP associated with the family haplogroup, R-BY99282, can be found on Family Tree DNA's new Discover More tool. A link to the page has been added to the Strickland DNA Project's Links page. The Time Tree shows the Strickland family branches that have been identified with BigY testing. The SNP associated with the group has a red icon. Once on the Time Tree page for the Matthew Strickland group, you can then go to the Scientific Details page to view information about the predicted age of the SNP, the Haplogroup Story page, the connections pages, the Suggested Projects pages, and other informative pages about the Matthew Strickland family SNP.

Family Tree DNA's new Discover tool currently provides an estimated Time to the Most Recent Common Ancestor (TMRCA) for the man who first had a SNP.  The tool predicts the first man with the "Matthew Strickland family haplogroup" R-BY99282 was born about 1571 CE and within a range of years between 1427 and 1684 CE with a 95% confidence interval (CI). This is earlier than Matthew's expected birth, suggesting Matthew may not have been the first Strickland to have the SNP.  The project is in need of a descendant of Thwaite Strickland to also take a BigY-700 test to determine whether Thwaite also had the SNP or not. The BigY-700 test has the potential to help us determine how far back in time the common ancestor of Matthew Strickland and Thwaite Strickland lived.

The BigY-700 test introduced in 2019 is a game-changer. If you are a Strickland-surnamed man with Y-DNA results and haven't upgraded your test to a BigY-700, please consider upgrading to the BigY-700, especially if you know HOW you are related to early Stricklands. Feel free to e-mail me to ask me questions and we can look at your results to see how upgrading might benefit you and the Strickland Family DNA Project. My e-mail is available by clicking on my name on the left under Administrators (with the envelope icon.)

The project welcomes all Stricklands to the project. If you are just starting DNA testing, ordering a Y-DNA 37 marker test can be a good starting place. The project also accepts autosomal DNA test results.

Strickland BigY Y-DNA Results Update (5 September 2022)
-New BigY-700 results for Matthew Strickland DNA group (see Results Chart below)
-New Strickland Y-DNA branch identified
-Family Tree DNA's new Discover More tool (https://discover.familytreedna.com/)
-Current Strickland BigY Testing Goals and Needs
-General Fund Donations

The Strickland DNA Project currently has 14 BigY-700 test results for the Matthew Strickland group of matches. The BigY-700 test became available in 2019 and is a game changer for surname projects. The BigY-700 test is an exploratory test, testing millions of locations on the y-chromosome. The BigY-700 test identifies both a man's ancient branches of the Tree of Mankind but also recent family branches in the genealogical time frame. The BigY-700 test has become an important tool for family surname groups to identify more recent branches of their family tree using both Y-DNA testing and documentary research.

R-BY99282 - Matthew Strickland or Earlier??

All the BigY test takers related to Matthew Strickland (as verified by Y-DNA STR marker results) share Y-DNA SNP R-BY99282. These test takers are descendants of a variety of Strickland lines in recent generations, both geographically (but all in the southern U.S.) and genetically. These BigY test takers all share a common ancestor represented by the SNP R-BY99282. All of these southern Strickland lines are believed to be descended from the immigrant Matthew Strickland although only one of the BigY test takers can document their line each generation back to Matthew. Because the test takers represent several branches of the Strickland family but all share the same ancestral family SNP R-BY99282, it is likely that the immigrant Matthew Strickland also had the SNP R-BY99282. It is not known if the SNP originated with Matthew Strickland the immigrant or with an earlier generation. Testing a descendant of Thwaite Strickland of Connecticut who is a STR marker match with Matthew Strickland may give us more information on the timing of the SNP - whether it originated with Matthew or if it occurred earlier.

In July 2022, Family Tree DNA released their new Discover More tool that provides an estimated time for when the common ancestor for a haplogroup was born. The tool is still in beta and the accuracy of the date estimate will improve as more people test in a family group. Currently, the tool estimates the man representing the Strickland haplogroup R-BY99282 was born about 1600 CE with a 95% probability he was born between 1427 and 1692 CE. Matthew Strickland the immigrant's birth fits within this range of years.

Several Strickland BigY test takers are not grouped under a more recent branching haplogroup but have only been identified with the ancestral haplogroup associated with this whole group of Strickland test takers. This includes the one and only documented descendant back to Matthew Strickland who has taken a BigY test. Each of these test takers have private variant SNPs that have only been identified in the individual test takers. When other test takers on their branch of the Strickland family who also share their private variant SNPs test, these SNPs will be identified and placed on the SNP tree and add information about the Strickland family tree. The Strickland DNA Project needs BigY test takers who know HOW they are related to Matthew Strickland so that Strickland Y-DNA SNP branch points may be identified on the Strickland family tree genealogically and not just genetically.

R-FTB7455 - Frederick, Simeon, and Reuben Strickland lines

Within a few days of each other in late August 2022, two new BigY test results became available for the Simeon Strickland line and the Reuben Strickland line. With the arrival of the first set of new results, a new Strickland family Y-DNA SNP (DNA change) was identified when the SNP matched a private variant SNP with the Frederick Strickland line. The new Strickland SNP R-FTB7455 identifies a new haplogroup branch on the Strickland SNP tree with the Frederick Strickland, Simeon Strickland, and Reuben Strickland lines all belonging to the same branch, sharing a more recent common ancestor. Unfortunately, we do not know which Strickland man was the common ancestor of Frederick Strickland (b. 1741), Simeon Strickland (b. 1776), and Reuben Strickland (b. 1794), all born in North Carolina. 

The Discover More tool currently estimates the common ancestor for the Frederick, Simeon, and Reuben Strickland lines was born about 1700 CE with a 95% probability he was born between 1471 and 1833 CE. We know from lineages that the most recent common ancestor (MRCA) for the branch was no later than Frederick's father. Candidates for the MRCA include Frederick's unknown father or grandfather.

R-BY122303

Earlier another Strickland haplogroup branch, R-BY122303, was identified. Six test takers belong to this Strickland branch. Below this DNA branching point, two additional haplogroup branches have been identified, R-FT354025 and R-BY193790. Not all of these test takers belong to the Strickland DNA project. More information is needed about the lineages of these test takers before the Strickland branches of these Y-DNA SNPs can be identified.

The Discover More tool currently estimates the common ancestor for R-BY122303 was born about 1700 CE with a 95% probability he was born between 1490 and 1793.

Strickland BigY-700 Results Chart:

Current Strickland BigY Testing Goals and Needs:
 
1. Descendants of Matthew Strickland with lineages through multiple sons and grandsons are needed to test the BigY-700 to establish the framework of the Matthew Strickland family SNP tree. Any descendant of Matthew Strickland is welcome to add his BigY test results to the project, we just have an immediate need for those with well-established, documented lines to Matthew Strickland. The Matthew Strickland SNP tree is growing using results of those with brickwall lines, but we need participants with their traced lines all the way back to Matthew Strickland the immigrant to learn which Strickland ancestors the branching SNPs belong to.

2. A descendant of Thwaite Strickland to take the BigY-700 test to determine how closely related Matthew Strickland and Thwaite Strickland are. Do Thwaite Strickland descendants also have the Strickland SNP R-BY99282? Or do Thwaite Strickland descendants share an earlier Y-DNA SNP with the Matthew Strickland family?

3. Descendants of Peter Strickland of New London, Connecticut. We have one set of BigY results for the Peter Strickland line; we need additional results for the line to have the Peter Strickland SNPs identified, named and placed on the SNP tree. The Peter Strickland line is not related to the Matthew and Thwaite Strickland lines.

4. Any Strickland descendant from any part of the world. There are Stricklands living in all parts of the world and they are welcome and encouraged to participate in the Strickland DNA Project. Y-DNA testing does not need to start with the BigY-700 test. The 37 marker STR test is a good starting test to learn about Y-DNA testing and how a Strickland line is related to other Stricklands who have already tested. Y-DNA testing is only for men (only men have a y-chromosome) but women and men with other surnames can participate by finding relatives to take the test.
