Okay, so Joseph Kneale is living in Liverpool in 1851 according to census and was married to Margaret Quayle. Census shows he was born in I.O.M along with his father William (from marriage certificate). I have been told by a lady at the central library in Liverpool that they were supposed to sign a register on entry to the mainland but did not always do so. I am guessing that the William in question is one married to Ann Farragher as on IGI. Is there any way I can prove this?
