been doing some work on Marriage contracts - old deed #69 Michael is m/c for Patt Caine + Joney Quayle - summary -
dated 2 nov 1717;john caine + ann als corlett obo son pat;elinr quayle obo dau joney(her fa dead);to marry before st thomas day at kk michl;Caines to give half land;elinr to over + above joney's fa share 40s + bed etc;witt tho quayle x;jo caine x;court may 1718
This + will of ann Caine als corlet indicates ann's husband was John - no marriage found but elinor, margt + Patt appear to be bapt between 1686 + 1693 - there might be a deceased son wm as there is a bapt of a wm to a john caine just before this - my own guess given absence of marr is that Ann came from Ballaugh whose marr reg is missing

there are several as yet untranscribed wills of a john cain in Michael pre 1738;

Patt + Joney had at least 3 ch john,jony + patrick Joney cain als quayle will is probably 1741 (not yet transcribed) + pat's could be 1765 decree not yet transcribed

I'm off island at present so can't easily get access to these wills
