Saw your inquiry in the Pubic library in Decatur Ill.My Grandfather was Yelverton Peyton Lawrence.I wish I knew more about him myself.What I do know:
He married Sarah Yolton in Fayette County Ill but I don't know the exact year.I can look it up when I get home.I don't think they came from Virginia.I think they came from North Carolina, to what is now Sumner County Tennessee, to southern Illinois.Yelveton settled near Vernon Illinois.He and wife Sarah Yolton are buried in Marion County Ill.
He had four children who lived to adulthood and two who died near birth.The four were named:Mamie, William Peyton, Frederick Clark, and Cynthia.I am not sure of birth order.
I do not have e mail myself, but have given you my son's e mail address in case you want to reply through him.
What is your connection to Lawrence?Where do you live?R,LLL
