Thanks CaroleW - yes I've also had a reply from rockofages and he's confirmed there was just the one. I just wanted to confirm and not go off up a blind alley if by some remote chance there did happen to be 2 Hull coppers of the same age in 1911 with the same name, especially as it's not an uncommon name. He was estranged from our family when I was little but my 85 year old auntie recently gave me a photo (first one we'd ever seen) of him with my Gran in their 30s I would think. He later left her for another woman... so now I'm curious to know more about him, especially as my sister, his grand daughter, has a great family likeness of him - which of course we weren't aware of previously as our Gran didn't really tell us much about him - not suprisingly I suppose. Strangely though, we always considered my sister to be Gran's favourite so maybe Gran never quite got over him. Life's cruel aint it!
