The name Emma Swain sounds familiar. I've been doing family history, and I think I've run across her before.
I can't find Thomas Twain Baskin right now, though. I do know, however, that a Samuel Crawford Baskin was born in South Carolinaon March 18, 1809.
His father was Thomas Stuart Baskin and his mother was Elizabeth Harris Long. They moved to Alabama and, I'm not sure, but possibly to Arkansas (Southwestern corner) since a few of his children moved there.
Samuel married Selina Ledbetter and then Sarah Wright. I don't know if this helps at all, but I hope it does.
