Autosomal DNA Project - Captain Thomas Pitman and Joseph Wall

If you think you are a descendant of Thomas Pittman or Joseph Wall and have DNA results at gedmatch, please request to join the ancestor project there (under "Free Tools" at the main menu) - look for Ancestors connecting back to Captain Thomas Pitman or Joseph Wall of Colonial Virginia. Include why you think you are a descendant in your join request.

Recruiting for DNA Projects!!

I help with several Y DNA project (generally aligned with researching certain surnames).

The Pittman DNA Project seeks new Y-DNA testers. Please contact me, if you're interested, and we can see if yours is a good fit for the project. If your lineage may be part of the "Captain Thomas Pittman" line (see CTP DNA Study) there may be funding available to sponsor the expense. This is an international project, so it doesn't matter where you're located. See also the project page.

Also, the Wall DNA Project needs new testers in certain lines. I'm also interested in talking to Wall/Walls potential testers around the globe. project page.

I'm also actively recruiting testers for the Treece DNA Project and the Shuman DNA Project.

If you have interest in any of these projects, even if it's just to ask questions, please contact me, and I'd be happy to talk to you.

Biography

Jef Treece is a graduate of Purdue University (home page), and he worked in Electrical and Software Engineering until retirement. He is knowledgeable in software, databases, and associated technologies, including SQL, Python, Linux, spreadsheets, scripting and automating and web.

His hobbies include growing giant vegetables (current Oregon record-holder for giant field pumpkins URL, as well as a few Indiana records - field pumpkin, long gourd and bushel gourd) and of course, genetic genealogy.

He is a volunteer co-administrator and research analyst of the Treece[1], Pittman[2], Wall[3], Clegg[4], Shuman[5] and Place[6] surname projects at Family Tree DNA. In this role, he assists with the Y DNA and autosomal DNA study, matching, reporting and test advice. He also helps research records and genealogy of family lines represented in the projects. His top area of expertise is Y DNA and NGS tests such as Big-Y.

Based on DNA results and genealogy, he's a known patrilineal descendant of John Treece, b.1812 in Surry County, North Carolina. John, his 2nd GGF, is an active puzzle. John's biological father was likely an unknown Wall of Group A in the Pittman project. Ultimately, this line is thought to connect to Captain Thomas Pitman of Colonial Virginia.

Traditional genealogy has John as a son of George Treece, b.1787 in North Carolina, making John a grandson of Michael Treece, b.1759 in PA. These patrilineal connections do not hold up to DNA scrutiny. Numerous descendants of Michael, George, and John have DNA results available for comparison.

• Maternal relationship is confirmed by a AncestryDNA match between Jef Treece and T.Shuman, where the common ancestors are Charles Franklin Shuman (1880-1958) and Jessie May Hart (1879-1956), the actual known relationship is 2C, and the expected shared DNA is 229cM (Shared cM Project, version 4.0), and the actual shared DNA is 209cM.
• Paternal relationship is confirmed by a AncestryDNA match between Jef Treece and Carl Treece, where the known relationship is parent/child, and the reported relationship is parent/child, at 3480cM. Both also have Y-DNA test results, which match exactly at 111 markers.
