Grayson County is also a center for many branches of my tree...unfortunately when I was visiting the Grayson & Ashe NC courthouses & libraries I was focused on many of the other branches and did not spend enough time on the Delp/Delphs.
I'm unsure what is written at ancestry.com as I don't use it. I'm also unsure where the DNA trail will take us.
What I do know is that there are several Delp/h descendants working here, all trying to arrive at substantiated facts.
I know the 'shunned' story has been often repeated, but until someone provides a church document or some other source that corroborates that---it remains just a story.
1990's - present; Laura Moncrief has worked to locate facts about Peter Delp/h's ancestry and has drawn no conclusions so far.
This 2014 article by Brendon S. Burns does a good job of organizing the issues.
2021/2 Research done here by multiple descendants has shown that some of the speculation used to connect Peter to Hans Georg and the Montgomery County Pennsylvania family have proven untenable--the Hechler/Hackler family that interlocks with Peter's children in Grayson Virginia is now known to have been from York County PA and have no reasonable connection to the Delp/hs of Montgomery Co.
The Michael Shuler family may prove to be a more fertile research ground as their migration pattern is relatively consistent with Peter's. Much more research needs to be done......
