My husband is the great-great grandson of Sylvester Brown and Mary Hickman. In the family Bible it gives his name as Roman Sylvester Brown. My husband is descended from their son, Stephen Augustus Brown. Also, in the Bible it gives Sylvester's father's name as David. There was no further information. I would truly appreciate dates, if you have them and can give you descendancy if you would like. Feel free to email me.
