Margaret C. (Peggy) Adams b. 1822 was the daughter of William Henry Adams born bet 1773 and 1778 in Albemarle Co, VA and Sarah Head, the second wife of William Henry Adams. All that I know about Margaret and Eppy White Thornton is that they were married Jan 18, 1842 in Elbert Co.,GA.Don't know anything about Eppy Thornton, but there were several Adams who married Thorntons.
William Henry Adams was the son of James Adams, Jr. and Jane (Jenny) Cunningham.My line is one of their other sons John C. Cunningham.
John K. Adams,who posts a lot on this forum is from William Henry Adams and his first wife Catherine Mansfield.He is well versed on William Henry Adams.I will be happy to share what I have.
I am also interested in more information on Margaret C. and Eppy Thornton's line to fill in some blanks.
