I have just read the book Jefferson's Nephews by Boynton, Merrill. I found that: Thomas Jefferson Jr namesake of the President and his wife Mary Randolph Lewis had 3 children Robert Lewis, Peter Field, and _______ who? The Lewises were Presbyterian. I believe the third child to be Mary Abigail Jefferson. I would like to look at the Presbyterian Church Records for Albemarle Co for the years 1808-1815 to see if I can find these children. If you have any other suggestion or answere please forward it to me. Marita
