Hi Andrew, I previously indicated I'm interested in male Lock(e)s in the Norfolk area I defined, so I did't have anything on Frances Lock born c1751.
I've been unable to turn up any Ancestry.co.uk records for Frances, but an LDS IGI record shows two Frances Locks born during 1747-1757 in Norfolk.One was born c1752 and married 5/5/1772 in Cockley Cley to John Judd born c1750 in Cockley Cley.
The queryremains unanswered about what happened to Sarah Ellmer (not Elmer) after 1821, first wife of Jonathan (or Jonothan?) Lock (or Locke?) b1768 in Larling.Jonathan was convict-transported to Australia in 1821.
The birth county of John Locke b1716 in Coney Weston was Suffolk, not Norfolk, so again I don't have anything on him.
