Thanks, Frances.
The four bapts I saw on FamilySearch (with scans) in Ballaugh for Margaret Corletts between 1810 & 1814 were 27 June 1810 d/o Thomas Corlett & Mary Craine; 4 Feb 1812 d/o Wm C & Jane Mcnemaire; 24 Nov 1814 d/o Daniel C & Margt Corkill; and the one you posted bap 7 Feb 1812 d/o Wm C & Jane Cannel.
Do you know which one married George Kewley?

William Corlett & Jane Kewish married in Ballaugh 8 Dec 1795 and possibly had 5 children Anne 1797 in Ballaugh; Elinor 1802 b.Bride; John 1806 Bride; Catherine 1811 Lezayre; John 1813 Lezayre.

There was another couple William Corlett & Jane Kewish - or perhaps two couples of the same names - having (8) children bapt in Ballaugh between 1833 & 1848.
But I can't see any Margaret Corlett daur of William Corlett & Jane Kewish who could have been the one who married John Corkill in 1833.
But she was possibly the daur of one of the other two William and Janes.
