Dave, Thanks for the response. I have unverified information: Elizabeth Blackmore, bc 1774/77 of Kentisbury, Devon. Died c. 1855 at Barnstaple? Father is maybe William Blackmore and his wife Sarah? I do know that Elizabeth married Humphrey Coutney Benham on 11 March 1800 at Kentisbury (but only through the IGI Individual Records) Humphrey and Elizabeth had 6 known children: Humphrey William John George Sarah James
With William being the second son and Sarah being the first girl names, it would appear that William and Sarah Blackmore might be correct.
