Hello Averil
I do not have a copy of the parish register of Robert Cain & Margaret Crowe's marriage in Braddan in 1853.

I do have a copy of a parish register of another decendent's marriage.in Bride in 1859 giving full details of parents so they may be listed on Robert & margaret's .

I expect it depended on the Vicar at the time.

I will let you know when i get more information
