Except for the spelling, I think we share the same great grandparents; Matthew & Mary Maynor.(From what I understand, Mary's maiden surname was Maynor as well.)I descend from their son, Charlie Maynor.
Similar to your information, I too am given to understand that they (Matthew & Mary) came from Virginia.
They only other information I have on them is that Matthew had a brother whose name I do not know.However, I am told that the un-named brother had a son, Arthur Maynor, and that Arthur Maynor's sons were Roy, Millard, and Rufus.
