Thank you Frances.
On the Jurby Register micro film at the museum for the marriage 1st May 1785 it says
william corlett & Anne Cowley both of this Parish married in this church by licence this the first day of may in the year one thousand seven hundred and eightly five by me wm crebbin, vicar, no parents names, no witnesses??
I could not find any William Corletts baptised in Jurby about 1755/60.
Ballaugh had four possibles and Lezayre 2.
