likely parents -
In Guilford Co, NC, Quaker minutes, Phillip Hamm and Priscilla Sanders had a daughter Jane b 15 Mar 1771 (Hinshaws were originally Quakers). Their marriage recorded in Deep River MM when Priscilla was "disowned for marrying out of unity [26 Dec 1767]". Benjamin Hinshaw of Stokes Co, NC m Annis Bowman of Deep River MM - so there is a possible connection. Priscilla is daughter of John Sanders and Jane Crew.
