I think we are working on the same family line. I have a Sarah Ann Doggett b. abt 1748, daughter of George Doggett and Ann Chattin (Culpeper Co. VA). But, my information shows that she was married to Benjamin Reynolds. I have no information on him, at all. Do you think that his name might perhaps have been Benjamin Richard or Richard Benjamin? My Sarah's father George is listed in my information as having been born in 1695 in Lancaster Co. VA, and having died in 1758 in Culpeper Co. VA. I have this George's line back to Richard Doggett, b. 1481 in Groton Suffolk England. There MUST be a connection here. Too many similarities.
I also have that "Miller Doggett" that you spoke of as being brother to Sarah Ann.. and Miller, b. abt 1741 in VA, d. Apr. 1807 in Jefferson Co., married Mary ?, is my direct line.
