Hi Glenys

On checking my Qualtrough database, I find that the Jane Corrin who married William Qualtrough 9 August 1865 at Rushen was baptised in Rushen 30 November 1834

This info can be corroborated in the 1881 census where she is aged 47 and living (as a Fisherman's Wife) at the Level Inn with her sister? (probably in-law) Eleanor Corrin (head), also a fisherman's wife and several children. Also present in this household is Ann Corrin, mother (also a fishermans wife) aged 86 and born in Ireland. I do not know who the father is...

So guess that about eliminates your theory unfortunately....sorry.

Kind regards
Elizabeth
