If you are still looking for information about this Thomas Sanders (and if your email address is still valid) I have quite a bit of info to share.
Thomas is from my DNA group. I am descended from his sister Frances (Fanny) Sanders, who married William (the elder) Sanders before 1776 in Orange/Caswell Co., NC. Thomas and Fanny were children of James Sanders, b. abt. 1705, New Kent Co., VA; d. 1776 in Orange/Caswell NC. James was the son of James Sanders Sr. and Sarah Scrimshire who married in 1698 in New Kent.
Please contact me if you want this info.
