Ann Rowlett was the daughter of Thomas Rowlett and as per Chesterfield Co. Will Book 3, pages 257-259, 1780,she was married to a Cousins. I was not sure of his first name but I had it as John and that one of his sons was George.
I believe that 1750 is somewhat early for her marriage since her siblings were born in 1748, 1755, and 1759. I have Ann's birth date as about 1743.
I'm not sure what information you might want but if I can be of help let me know. I would appreciate information you might have showing Ann's husband as George.
