Hi
Did he go by his birth name, or did he take on his adoptive parents' names?
If you could tell us where he was born, and which censuses you have found him on, plus the name he went by so we can help.

He was known by his birth name Frederick Jackson b.1882 with adoptive parents Luke and Hannah Abbey and their daughter Sarah Ann at St georges court york in the 1891 census.He married Bridgett Davitt in 1911 and the wedding certificate states fathers name John.
I have suddenly realised I have asked this question before although it was quite some time ago (maybe there is more info available now) it is still driving me mad trying to find out.
