The most distant ancestor that I have been able to identify in the strictly female line of descent is my 2-great grandmother Mary McQuien, who was born 13 July 1832. I do not know where she was born nor do I know where she married my 2-great grandfather John English Autry. The only thing that I know for sure is that their families both appear in the US Census for Sumter County, Georgia, in 1840. Her father was John D. McQuien and his was John Autry, Jr.
I am most interested in hearing from anyone who might know more about this John D. McQuien.
