The Crockett Families DNA Project - Results

As of March 26, 2017, there are six emerging family lines and ten matchless participants. At this point in time, there is inadequate documentation to prove that any of the Crockett DNA project members descend from Antoine de Crocketagne. Many, if not all, Crockett's would like to claim him as an ancestor but for anyone to do so with inadequate documentation is pure and imaginative speculation. Our DNA project has proven that many of the Crockett lines French and Armstrong connected in their book "Notable Southern Families - The Crockett Family" are unrelated by blood. Any one of the Crockett DNA participants has as much claim to Antoine as any other because adequate documentation has not been found on this particular Crockett family. Perhaps one day we will know more on this subject.

These are the participants within each of the six distinct Crockett family lines identified by the Y-DNA project as of this update:
1. Ray Kenneth Crockett (31955), Stanley Theodore Crockett (30942), David Dawson Crockett (32026)
2. Alan R. Crockett (31269), Jeffrey D. Crockett (31306), James Hansel Crockett (31248), Ronald W. Crockett (32222), David Crockett (32187), David Crockett (40885), James Lenoir Crockett (39766), Robert Richard Crockett (60608), William Edward Crockett (78359), David C. Crockett (65823), Mark Frederick Crockett (213839)
3. Mark Paul Crockett (42997), John Melvin Crockett (45737), Garland Crockett (50716)
4. Scott Douglas Crockett (50871), David Nelson Crockett (95589), Herman Boyd Crockett (78056), Private Kit# (159057) No Family Information Made Available
5. James Edward Crockett (31983), Edward Aloysuis Crockett (32235), Shawn David Crockett (50382), David Wayne Crockett (68466), Private Kit# (91204) No Family Information Made Available, Larry W. Crockett (83171), Edwin Crockett (113008), William G. Crockett (142086), Jeffrey Don Crockett (144083) Christopher Crockett (392910)
6. John David Crockett (35094), David Wilmot Crockett (209273)

Those participants within each line are related to each other through a common ancestor. However, those within one line do not share a common ancestor with participants in any other line. These nine Crockett's remain without any match so far:
7. Nolen Jewell Crockett (31249)
8. Joseph Bennett Crockett (39052)
9. Private (57951) - No Family Information Made Available
10. Adrian Graham Crockett (56503)
11. Private (92791) - No Family Information Made Available
12. Private (109412) - No Family Information Made Available
13. Eric Parker Crockett (292385) 
14. Thomas Carnie Crockett (92791)
15. Eric Parker Crockett (292385)
16. Private (395408) - No Family Information Made Available

Only three of the above has ordered the SNP (single nucleotide polymorphism) test for haplogroup confirmation. But using FTDNA prediction and the calculator page Lee located at, it appears that all participants except those in family line 2, 7 and 8 above are at least a “fair fit” for haplogroup R1b. The participants in family line 2 (31269, 31306, 31248, 32187) are all a “good fit” for haplogroup I1c. [Note: The term "haplogroup" refers to deep ancestral origin.] FTDNA explains these haplogroups as follows: "Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. This lineage is also the haplogroup containing the Atlantic modal haplotype." "The I, I1, and I1a lineages are nearly completely restricted to northwestern Europe. These would most likely have been common within Viking populations. One lineage of this group extends down into central Europe." Haplogroup I1c is explained in this quote from a journal article abstract at the National Institutes of Health website: "Subclade I1a accounts for most of Hg I in Scandinavia, with a rapidly decreasing frequency toward both the East European Plain and the Atlantic fringe, but microsatellite diversity reveals that France could be the source region of the early spread of both I1a and the less common I1c."  (

Participants with kit numbers 31269, 31306, 31248 and 32187 fall within haplogroup I, suggesting Nordic deep ancestry. FTDNA says, “The I, I1, and I1a lineages are nearly completely restricted to northwestern Europe. These would most likely have been common within Viking populations. One lineage of this group extends down into central Europe.” At the Y-DNA 12-marker level, kits 31306 and 31248 are exact matches. Both 31306 and 31248 match 11 of the first 12 markers from kit 32187. The one marker mismatch is at DYS #385b, which is considered a fast moving (mutating) marker. FTDNA states regarding fast moving markers that the “current estimate of distance between 2 people [who] are related is probably overstated, and they are more closely related than could be assumed by the distance suggested by a standard single marker deviation.” Therefore, kits 31306, 31248 and 32187 may be considered nearly exact matches at the 12-marker level. At the Y-DNA 12-marker level, kit 31269 also deviates from 32187 at fast moving marker 385b. However, after calculating the effect of differences at DYS #389-1 and #389-2, and allowing for the overstatement of the mismatch at DYS #385b, kit 31269 still shows a single mismatch. This indicates that 31269 is related to 31306, 31248 and 32187, but suggests the possibility of a most recent common ancestor (MRCA) who lived in an earlier generation than the MRCA shared by 31306, 31248 and 32187. At the Y-DNA 25-marker level, after allowing for the overstatement of the mismatch at fast moving marker DYS #385b, kits 31306 and 32187 are nearly exact matches. After allowing for the overstatement of the mismatch at fast moving marker DYS #458, kit 31269 in effect matches 24 of the 25 markers of 31306, 31248 and 32187. After allowing for the overstatement of the mismatch at fast moving marker DYS #385b, kit 31248 in effect matches 24 of the 25 markers of 31306, 31269 and 31287. Y-DNA results at the 25-marker level indicate that 31306, 31248, 31269 and 32187 are closely related. All claim to be descendents of David Crockett the elder (c1727-1777)—31248 through son William, 32187 through son John, 31269 through son Joseph, and 31306 through son Alexander. The Y-DNA results seem to support the genealogical claims. It is possible that the MRCA lived one or two generations earlier than David the elder. However, in the absence of any other candidate who fits the genealogy, David the elder appears to be the MRCA for 31306, 31248, 31269 and 32187.

The twenty-five marker Y-DNA test results show that Kit# 32026 & Kit# 30942 match Kit# 31955 24 of 25 markers. They differ by one point at DYS #439, a marker known for slow mutation. Based on the 25 marker test, there is a 79.10 percent probability that Kit# 30942 and Kit# 32026 shared a common ancestor with Kit# 31955 within the last 300 years. Kit# 30942 and Kit# 32026 match 25 of 25 markers and there is a 94.15% probability that they shared a common ancestor within the last 300 years. Additionally, Kit# 30942, Kit# 32026, and Kit# 31955 belong to a rare haplogroup where DYS393=12 and are classified R1b1c Ht35. There is an ongoing DNA study on Scottish Border Reivers that is researching this rare haplogroup. DYS393 is an extremely stable marker. The URL address is: Quote from Bennett Greenspan, President of FTDNA, regarding the Scottish Border Reviers DNA project samples where DYS393=12. “The defining aspect of all these samples is that they have a 12 at DYS 393...very uncommon for R1b, as 90+ % of R1 is found as a 13.”

Three theories on why DYS393=12 is found in Scottish Border Reivers:
1) the 5,500 Sarmatian troops stationed in Cumbria and Lancashire during the Roman period. These troops were armored cavalry, eventually settled in Northwest England, and were presumably assimilated by the native populace. Some scholars have speculated that the King Arthur legend sprang from tales of the Sarmatian cavalrymen and one of their leaders, Lucius Artorius Castus. The Sarmatians - like the Alani, who colonized parts of France and Spain - were an Indo-Iranic or Turkic tribe originally from the Caucasus, and some of their direct descendants still live in the Caucasus under the name Ossetians. Other possible vectors include:
2) Norman families that were originally of Scandinavian, Burgundian, Alsatian or Visigothic descent, and
3) Norwegian Viking settlement of the areas bordering the Irish Sea.
