Hi Donna: I'm sorry but I know nothing about this particular Cain (I do have Cain(e)s in my tree however. I am transcribing the LDS Will films presently held in my local FHC that were ordered by Brian Lawson. Brian paid to have these kept permanently in the centre, however the Church opted to return them to Salt Lake upon his death, not realizing that I was also researching my Manx lines. I have made an arrangement with the Church to keep these films and not send them back to Salt Lake (which is their ultimate intention). I'm attempting to transcribe as many as I can (I will NEVER get through all of them). The Will for Katherine Mcylrea Cain dated 1696 is only one of many that I've managed to get to so far.
