Hi Helen! We would need a bit more information to go on. Could you include his birth year as per the 1911 Census? Also his father's birth year? Any other family members mentioned in that Census? If you could start a profile for him with all the info you know so far, including his wife and kids, that would be great! A link to the 1911 census mentioning him would be super too!
Meanwhile, i'm puzzled by the mention of the Easington census in connection with the Isle of Man as the residence. Is the Isle of Man showing as the birthplace of your great-grandfather? It would seem he was residing in Easington, which is not a town on the Isle of Man. There is an Easington in County Durham, is that the place where they are enumerated in 1911?
I'd really like to help, but just need a bit more info for starters
Cheers
Shirlea
