Sorry I didnt realise you had no connection until after I posted.
Im sure my grandfather is Robert, on his marriage cert he didnt put a father on it. The birthcert I have gives the fathers name as Barney and an address at 2 Harmony Row.
I have looked into the family census you mentioned but no clear evidence So I was hopeing to get something more concrete from Catherine with the same address.
Good luck and Happy xmas :)
