You might want to also check Greensville, Sussex and Southampton Counties, VA. I have a cousin who is a Seabron, Seaborn(e) descendant. He is also has the Vaughn surname in his family from the same area as above. Some of the white families living in the above area during the Nat Turner Revolt left the area. I believe the Vaughns migrated to GA then to Al then back to VA. I am writing this from memory, so am not real sure of the exact story. I believe the oldest known relative in my cousin's family was Ben Seaborn born in the 1700s in Sussex County, VA.
