Everyone has her name as Mary Hardy, Mary Benton, and the latest version I found is Nancy Benton. The whole problem is, there are hundreds of people of this line, and no one can supply any proof---not even proof of any hearsay. Just because a name has been handed down in a family, does not make it be her last name---that's why one group has Hardy---the other group has Benton---and now lots of people are calling her a Hardy-Benton---combining the names. My daddy's name was General Lee, but that sure does not indicate we are descended from General Lee.
As for Isaac Holeman (JR.)--I was given that he was born 20 March 1757 Rowan Co.,NC, and married twice--one to Catherine Wilcoxson, and 2nd to Lillis Nichols.He died 5 April 1843 Clark Co.,IN. Do you think this is that the one you are asking about?
