Thanks Frances. If there were only 2 Isabel Corlett als Kneales it would be easy as there's another one in Brian's index buried in Lezayre in Oct 1828. He also has several Lezayre Isabel/la Corletts, no alias given, in the 1770s and 80s, not to mention, as you point out, those from the 1790s which I haven't seen.
