Do you by any chance have Thomas Caine's birth or christening date, more specific than 1812? I have a Thomas Cain, son of Thomas and Ann (Killip) Cain, bp Braddan June 5, 1813. Thomas Cain, Sr., died, and Ann remarried in Lonan. I have never been able to find out what happened to Thomas, Jr. (He is not mentioned in his mother's will, but is mentioned as a child unborn in his father's will.) Thomas and Ann (Killip) Cain had another son, John, born in 1810, but he was not mentioned in his father's will, and I think he had died, although I have not yet found a burial.
Do you know when Thomas and Margaret emigrated?
Looking forward to hearing from you.
