Samuel Turner Reed (Sr.) is also my 3rd g grandfather and I would love to share information with you. He has been one of my problems. I descend through his son, Samuel Turner Reed (Jr.) who married Sarah Margaret Bankson.
I have his second wife, Fanny, but only stories of another earlier marriage so anything would help. I think he also had a 3rd wife, Ruth Clary Swearingen; I'm not sure which is her maiden name.
I haven't figured out their children as I only have the census information.
