For Thomas PINDELL (son of Thomas PINDELL and Jayne/Jane (nee?)) and Mary BELT, I have 2 children:
Richard PINDELL b.abt 1751 poss. Prince George's Co., MD - d. 20 Mar 1833 Lexington KY.m. Elizabeth Hart (daughter of Thomas Hart)
Mary PINDELL , b. abt. 1753
For Mary BELT and Edward SPRIGG I have 1 child:
Lucy Belt SPRIGG b. 1752 Prince George's Co., MD - d. 1 Dec 1823 Hagarstown, Washington Co., MD.m. abt. 1773 Nicholas Dorsey (son of Henry DORSEY and Elizabeth WORTHINGTON).
I don't have solid documentation on any of this, and as you can see, Lucy SPRIGG's birthdate and Richard PINDELL's birthdate can't both be right.However, both Richard and Lucy were mentioned in the will of Thomas PINDELL.
I have no children listed for Mary BELT and Edward HALL.
I have a bit more information on the PINDELL family, if you are interested.
