Probably not then as this one seems to have had 7 kids. The 4 kids names you mentioned actually match 4 of the 6 of a William Killip b 1701. The info is from my Father Robert and Uncle Alan who both still live in the IOM. You have had dealings with Alan before. Trouble is that the info I have is now about ten yrs old and probably needs updating. My dad isn't bothered much now but I think Alan still does it. Trouble is none of Alans records are computerised so it is hard to delve.
