I show three Seaborns - One is the son of John Carroll b-abt 1754 and Rebecca ______? He married Chasey Ivey b-1807 NC d-1880 in Alabama - they had eight children: Piety, William, Thomas Haywood, Richard Bryant, Seaborn b-1841, Carey C, Marion and James Robert Carroll.
I also show Seaborn Carroll b-1836 - the son of William Carroll and Piety Hobby.
I am not positive on any of these, for I have yet to confirm them - but this is what I have been sent by others claiming to be related as well. Seaborn is a rare enough name to not get mixed up as a William, James, John, etc.
As far as Jacob Carroll's siblings - Which Jacob - I have about five of them. There are ten Jacobs listed on the internet. I am descended from the Jacob Carroll b-1805 NC, that married Milly Branson.
