If no one in your family has participated in the Hooper DNA Project, I would like to suggest that would be helpful to find out if there is a match. Since your last name is Pollard, I am assuming you descend from your maternal side of the family. If you know any direct male descendants, please encourage them to participate. This is the site in case you are not familiar with it:
The Will of Joseph Hooper in 1842 Hardeman County TN listed daughter Nancy Hooper, daughter Kiziah Hooper, daughter Martha Hooper, son Richard's heirs, daughter Lucy, son William, daughter Sarah Hickman's heirs, daughter Elizabeth Mauler, granddaughter Eliza Hooper, daughter of Sarah Hickman and grandson Jeremiah Hooper. We have not found the father of Joseph Hooper.
