This is a different Ian Killip than your previous contact - confusing eh?! It seems as though your thread was hi-jacked by the search for Larry's Thomas! (sorry Larry)
I assume your parents are Richard Killip and Mona Moore and your grandfather,Warren L Killip born in 1922 in Rochester New York.
Have you managed to obtain any other information about your ancestors? It is difficult to establish ancestral lines of people in the British Isles because of the 100-year embargo on personal information imposed by the British Government. To have a reasonable chance of discovering where your family originated (the Killips would certainly have originated in the Isle of Man some time within the past two hundred years) you would really need to go back at least to Warren's parents and preferably a further generation when there would likely be other Killips with information about your ancestors.
