Are there enough Herdmanston DNA hits to target geographical areas in Scotland for ancestry searches? East Lothian would seem obvious enough, but how about Argyleshire, Renfrewshire, and Ayrshire?

There are a lot of hits in Argyle, but they're a different SNP. Your best bet in East Lothian. Participantion from UK residents is relatively low - security concerns likely, so we may not get much help there.

Hello All. This is Kathryn from New Orleans. My great-grandfather FW Sinclair moved here from Gloucester, Virginia area to marry my sweet great-grandmother back in 1907. This line of Sinclairs has been in the Mobjack Bay/York River/Rappahannock River region of VA since the 1730s. I'd like to learn which DNA group my line of Sinclairs belongs to. Being a lady, I can only learn my mtDNA so I'll rely on the family men to share this information. I appreciate your time and attention to my request. Thank you!

I suspect you'll be related to Alexander Sinkler given the Rappahannock River region you mentioned. Do you have men in the family who carry the surname and can do the DNA testing?
Steve St Clair

My advice is to trace forward in FW's line moving toward the present. Try to find living male descendants to test that way.

While Jenkins by name I am actually a Sinclair by birth. Over the last two years I have been blessed to find, by the help of volunteers, my family tree, and my birth parents. As best I can, I am trying to recreate the lost family ancestry. I am waiting for my Y-67 and R-A8055 studies to complete to give me more resolution on where I come from. On to my question, does anyone have ancestors that ran through Michigan? I cannot find a connection for my second great grandfather, George James Sinclair George James Sinclair, 1852–1928 BIRTH 3 JUN 1852 • Royal Oak, Oakland, Michigan, USA DEATH 19 NOV 1928 • Highland Park, Wayne, Michigan, USA His death certificate shows his parents as James Sinclair and Alice Nobley. This is where I may have run out of leads. I am researching a couple that seem to be in the right dates to be his parents, but find no connection to him. There names are James A Sinclair and Alice Mobley. They married in Michigan and ended up in Iowa, assuming there was not another James and Alice running around at the same time and place. As I mentioned, any family history that is lost past my grandfather. I have already uncovered facts that my father had never heard of about his grandfather. So, I have no one in the immediate family to use as a resource. As I am adopted, and recently found, I don't know anyone past my father and his sister. Thanks in advance for your time!

Scott, I ran a search on Ancestry and found a George James Sinclair with the correct dates whose wife is Agnes McDonald and whose parents are James Armstrong Sinclair and Martha Alice Mobley. I found George's death certificate of 19 Nov 1928 which gives his wife as Agnes McDonald and his parents as James Sinclair and Alice Nobley. James Armstrong Sinclair was born 17 Oct 1827 in Walls, Shetland, Scotland, and died 17 Jun 1905 in Spokane, Spokane, Washington. His parents are Robert Sinclair and Margaret. I found a marriage record for James Sinclair and Alice Mobley in Detroit, Wayne, Michigan, on 30 Nov 1848. I found a Robert Sinclair, born 2 Jun 1805 in Northmaven, Shetland, Scotland, whose father is Magnus Sinclair and he has a child James Armstrong. Robert's parents are possibly Lesslie Sinclair and Elizabeth (1841 Scotland Census). There is a record of Robert Sinclair being baptized in 1807 in Delting, Shetland, Scotland, and his father is listed as Leasly Sinclair. I don't know if this will help, but here it is.

Thanks. I am also on Ancestry. If you found the Sinclair and Hubble tree, that's me and may be were that info came from? James Armstrong and Martha Alice are shots in the dark that may, or may not, produce fruit. Their dates work, but what is lacking is anything showing that they had a son named George (not counting my tree). There is also another public tree our there that was set up to test this theory, but does not prove out George yet.

The death certificate is documentation, or are you looking for something more?

I’m just starting my Redman-Sinclair/St Clair/Sinkler research and a Redman researcher had mentioned that there were a couple of high profile marriages to the well known Sinclair family in the UK. He mentioned that there was info on a large clan with surname changes but couldn’t remember the full original clan surname ... it was Mc"something". Does this sound familiar to anyone? I’m thinking the NPE occurred in the early 1600s when my Sinclair/St Clair/Sinkler became a "Redman/Redmond".
Scott Sinclair Scott Sinclair has a question!
May 29 @ 4:09pm
With DNA matches between myself and Scott Jenkins and genetic distance being 0, how many generations could we conceivably go back before we find the "common link" (hopefully not an ape :-))?
Scott Sinclair
May 29 @ 10:18pm
I think Scott and I match on 67.
Scott Jenkins
May 30 @ 10:08am
Correct, we match through 67 markers.
Steve St Clair
May 30 @ 9:25pm (see previous post of chart) analyzes the tons and tons of Big Y data that comes in and does time estimates for shared male ancestry. For the Herdmanston lineage (which includes some in the Forrester family and an ancestral descendant of the family ID: YF06742) the connection is on A8062 which shows a Time to Most Recent Common Ancestor of 550 years ago. Using SNP connections from Big Y is far superior to FTDNA's old TiP calculator for genetic distance, though that tool is sometimes proven accurate by Yfull.
Steve St Clair
May 30 @ 9:30pm
With a genetic distance of zero on the 67-marker test, Scott S. and Scott J., you two likely share an ancestor since the 1700s.
Steve St Clair Steve St Clair
May 30 @ 9:19pm
As you can see, the TMRCA of the Herdmanstons and Forresters is currently showing as 550 years before present. This can change based on numbers of people tested, and especially when we find older connections to test, like the recent work we're doing on the connection between our Ancestral Caithness lineage and the Cummings (Comyn) family. More on that coming this weekend. There is still much to discover thanks to Big Y and my affinity family approach.

Greetings Fellow Researchers, I am searching for descendants of Charles St. Clair of St. Clair's Bottom, VA. We have reason to believe that our line of St. Clair's is descended from his daughter Catherine Deborah who was married to William Pruitt (Fort Nashborough, Davidson County, TN and the Cumberland Settlements). Our lineage may be via a NPE Non Paternal Event regarding an illegitimate child born in 1787. Any help would be greatly appreciated.

Hi Steve is Craig Sinclair no longer involved with this group? its important to me because of who we dna match in common namely Colin Stewart and the Corsica Stuart we all match (Bonkyll lines) my 2 paternal Stoddard uncles also match Corsica Stuart , along with my maternal 1st and 2nd cousins side do too (I have Stewart both sides) Boswell and Smyth has something to do with the Corsica links, and Cromwell used Smith / Smyth as a pseudonum (we have Cromwell) And Boswell who wrote " Journey to the Hebrides" (Auchinleck) same area as our Douglas, Maternal is Glenbervie Red Douglas Angus lines Douglas is on both side (as is Stewart and Sinclair) on my paternal many Mayflower lines is also many Magna Carta Barons , Randolph, Earls of Morton , and Angus Douglas, Stewart and Bruce and Bonktyll , I descend from Henry Sinclair who built Rosslyn , and royal stuart / Stewart my paternal uncles William Stoddard DNA was of interest to Craig for sometime as we have a rare SNP A2150 . I emailed him (with no response) to show we share DNA T967165 7.5 7.5 7.4 7.5 7.5 7.4 0.0 CraigSINCLAIR (rest of email removed) the complex thing is I have royal stewart both maternal (Bonnie Prince Charles) and Stewart Paternal in England late 1600s, which I'm totally stuck on I'd like to be able to work out the links between our combined matches and surnames Interstingly surnames similar to Herdman / Herdmanston are popping up in DNA matches, and separate from the Rosslyn Sinclair line it seams Sinclair, both sides of family; way back and of course Stewart and Douglas often married Sinclair lines. we also descend from Clare and Claret (which may well be same) french there frustrating thing that being female it seams theres not much help. I also DNA match on the Sinclair dna project I match on the Sinclair DNA project both (we share lots of same surnames) Matthew Bryon Smith and James Sinclair Denton and de Hann

BTW, Hardy is my ex-husband's name, but I do kind of have a Hardy in my family tree. My 6th great grandmother Anne Cope was married twice. Her first husband was John Madden, my 6th great grandfather. Her second husband was John Hardy (1718-1775), birth place unknown, but he died in Loughgall, Armagh, Northern Ireland. They had two children: William Hardy (1751-1817) who lived and died in Loughgall, Armagh, Northern Ireland; and Mary Hardy (1760-1809) who married Anthony Chambers ( - 1804)

Sorry, Jackie, I forgot the rest of your question. I have a huge tree on Ancestry. I have a smaller one here that you can see by clicking on my name and wait for the family tree symbol to come sliding in at the top right hand corner. My Ancestry Tree is "Andrews Family Tree by ghparalgl".

Hi, Thank you for approving my request to join. I just found out that I might be a Sinclair descendant. According to Geni, my line is via my Ezell, Rose, Chisholm, Stewart lines. I have not been able to verify the line by paper and DNA is showing i have a lot of Sinclair and Stewart dna matches.Would love to figure out how i connect and look forward to sharing and getting to know everyone! My kit number is 305042. Sincerely, Kelly
