From the notes of Robert Legg: "Some researchers try to say she was a Petty. Let me explain the history and you will see why the mix up.Thomas Legg 1660 and Christopher Petty went to Richmond County, VA together and had land grants adjoining each other, they were closefriends. Thomas 1660 married a Sarah Lnu and had a son, Thoms 1700. Thomas 1660 then died. Sarah then married Christopher Petty and had two children by him, Christopher and Prudence. (Mentioned in different sources, the clearest is PANTHER MOUNTAIN PIONEERS, By Thelma R. Snowden).So, Sarah was a Petty, but only after Thomas died and she married ChristopherPetty."
