Looking for Information of Jesse Pursley of Virginia 1776

I have started to research my Pursley family background. I have traced it from Farmland, IN to a Jesse Pursley born in 1776. I now would like to trace this further back, who were his parents, where did they com from and when did this part of the Pursley family come to America. I'm at a standstill and would appreciate any help I can get.
