Hi Douglas - I'm a bit confused by your question. Are you interested in "Patrick Moughtin m Judy (Joney) Quayle 24 Jan 1789 Kirk Jurby", or in "John [Quayle?] m Catherine Moughtin"? Are you saying Patrick Moughtin & Joney Quayle's daur Cath married John Quayle?

Patrick Moughtin & Joney Quayle also had a son John Moughtin bapt Jurby 12 June 1803, who married Jane BREW in Lezayre 18 May 1850 whom I have information about, but I don't think that will help.

Was their daughter Cath bapt in 1800?

If so she is most unlikely to be the Catherine Moughtin who married John Quayle in Maughold on 27 Nov 1814 (John from Lezayre), who look like your Lezayre ones.

How about CATHARINE MOUGHTIN Christening: 16 DEC 1787 Jurby, Father: DAVID MOUGHTIN, Mother: ELISABETH CLARKE? [IGI]

What is her birth place on censuses?
