Difinitely have Thomas as the Shoemaker on the marriage cert of John and Emma - then again who says that the certs are that accurate anyway. When I registered my own kids births you can tell them whatever you like and they don't check. The familtysearch site seems to be compilations of data and you quite often get the same child appearing twice on the family lists. It also doesn't trace back the same way the one my father ( "Roy" really Robert ) gave to me. The trouble is now one of too much information that doesn't match. Incidentally if you click on the source of the info it turns out to be a nobody who is not a Killip. Is the "Thomas who married Hannah" the 1824 born one son of Thomas and Ann Killey ?
