I have been searching census info for ransom....he would have been my gg grandfather.I've heard several birth places, including Indiana, Mississippi and South Carolina. I've also heard he was born in 1832 and also heard 1834.
In my searching, in the 1860 census I've found the following Ransom Allen's (by age..they hall had the same name)
