Now as for the Vortimer vs Vincent as a middle name, I’m not sure where either information is documented as to either name. I was looking at Vincent P Adkins’ records, that entered the USA on Ellis Island and I didn’t see any full middle name there either. One of the younger Parker’s lists Vincent as his middle name so it stands to reason that it possibly came down from that.
The Cherokee & Shawnee Researchers have researched and/or obtain most of the Revolutionary Fort documents to base their findings among other paperwork that they have.
Thanks for you comment.
