I just want to thank everybody for their fantastic help and guidance.
As a result of which I've managed to trace Catherine Cain (nee Craine) living with her son Thomas in Onchan and other members of her family thru to 1891. She is enumerated as Catherine ANN Cain.
Matthias seems to have died between 1855-1861, as she is a widow in the 1861 census.
Thanks for pointing me towards Ann Lawson's information.
it appears that one needs to join the IoMFHS to get access to the full information which is really frustrating as I'd love to see them.
It really does sound as though this is the right individual though - baker seems to be a consistent theme throughout the years.
If anybody can help me further I'd really appreciate it.
Just want to add that this forum is a wonderful new resource to me.
