According to what I've picked up on this site from other members in addition to the family history, Elizabeth's maiden name was Mallory and she was born in 1770.I have Richard as having a sister named Sarah, but no daughter.His other siblings were Ann, Presley b. 1723/24, William and John. I have his children as Presley b. 1751 d. abt 1834, Ann b. abt 1740, John b.1740, d. 1787 and William b. abt 1740, d. 1783.I also have Richard's mother listed as Sarah b. abt 1692. I would also be interested in your source for his daughter. Richard would be my gggggg grandfather. Hope this helps!
