Pennsylvania Land Deed: Vernon, Cheyney, Williamson, James

Kathy Wilson sent me names from an early land document (a deed) in Pennsylvania. It's a deed labelled "Jacob Vernon & wife to Abraham Williamson & Jesse James [Jameson?] &wife to Abraham Williamson"

Witnesses were Thomas Cheyney, Mary Cheyney

Signatures: Defoe James, Elizabeth James
Signatures: Jacob Vernon, Sarah Vernon

I did a little checking online and found that Jacob Vernon (1708-1748) married Elizabeth Cheyney and had a son Jacob Vernon (1745-1787) who lived in Chester Pennsylvania. Jacob Vernon (Jr) married Sarah Frazer. I feel confident that Jacob Vernon (Jr) and Sarah Frazer are the signers shown above on this deed.
