It's been a while since you posted your query, so I hope this late post finds you and is helpful.
I didn't know I was a Thigpen descendant until I did DNA testing. I highly suggest doing so, especially if you know some of your family.
I was adopted as an infant in December 1967. I had some health issues a couple of years ago, so I decided to do genetic testing.
Via DNA, I've found many, many Thigpen relatives. I've contacted and talked with several close cousins. I haven't figured out exactly where I fit in as of yet, but I know a lot about my heritage now...starting with Jessie Stephen Thigpen and moving back all the way to the 16th century.
Recently, through DNA testing, I found that I'm distantly related to about a dozen people who are descendants of David Phippen, Owen Phippen's brother. David's descendants helped settle the Massachusetts Bay Colony while Owen's settled NC as Thigpens. Pretty cool, huh?
I took both the Ancestry and the 23andMe tests. I then transferred them to FTDNA. I also uploaded both tests to Gedmatch. I've gotten similar matches on multiple sites, which I use as confirmation that I am indeed related to those people. Yet some people are only on one site, so I also get new matches on each website that do not participate with other sites.
I hope this helps!
