Two of William’s direct male descendants will be submitting saliva samples soon for Y-DNA testing, and they will be participating in the EDGAR Surname DNA project. I am hoping (and expecting) that we will see a strong correlation between the results from their samples and those from the sample from my uncle, James D. EDGAR, that we obtained and submitted about two years ago as part of that project. He lives in Alabama, and his sample results are shown in Haplogroup I.
I have compiled quite a bit of information about Adam’s and William’s active involvement with the Reformed Presbyterian Church in Chester County, SC and William’s involvement with the RPC in middle TN (the Duck River Society) and in Sparta, IL (along with Samuel LITTLE, husband of William’s sister, Margaret Jane “Polly” EDGAR). One of the stunning things we’ve discovered in that research is that one of my wife’s relatives (one of her paternal 3g-grandfathers, the Rev. Samuel Brown WYLIE) was one of the representatives dispatched by the RPC Synod in Philadelphia to visit the RPC at Rocky Creek, SC and other RPC's in the south. SBW and James MCMILLAN did that, and they met with the Rocky Creek RPC Elders in Jan 1801. Adam EDGAR, who had apparently been a founding Elder in that church, had died by then. But, his son, William, was there and was an Elder then. We are pretty sure that our James was either one of Adam’s sons or possibly one of his grandsons (through Adam’s son, John). Based on the information in the Aug 1931 document written by Thomas Delbert EDGAR (Abt. 1868-1932), a copy of which I sent to you, I now think it's more likely that our James EDGAR (10 Sep 1790 - 29 Apr 1869) was one of Adam's children (along with William, John, Margaret, and Abigail and possibly others).
I have gathered quite a few EDGAR land records from TN from the early to mid 19th century. With some more time and with the benefit of William EDGAR's descendants' upcoming DNA analyses, we should be able to sort this out more clearly and more definitively.
Anything you and/or others might have or might yet find in the way of source documents or references that might provide some clues or proofs regarding the EDGAR family who lived in Chester County, SC in the late 18th century and who then left around 1808-1810 headed to middle TN would be much appreciated and very helpful. And, I'll be happy to share anything I have with you and others.
Thanks again for the response. I look forward to continuing to exchange information and ideas with you now that we’ve connected.
All the best,
P.S. Another “small world” discovery has been that the Rev. Samuel WYLIE (one of the Rev. Samuel Brown WYLIE’s nephews) who founded the RPC in Sparta, IL and who apparently helped persuade William EDGAR and his brother-in-law, Samuel LITTLE, to relocate their families to the Sparta (Randolph County), IL area in 1819 was also one of my wife’s relatives. He (the Rev. Samuel WYLIE) was one of her first cousins, 4X removed. My wife and I have been married 42 years and have known each other 44 years and we had no idea of this interaction of our relatives in the 1800s until about a year ago.
