Firstly I would like to thank you lizdb, Annette7 and Ladyhawk for your kind help, it is very much appreciated. I work away from home so I can't always reply as promptly as I would like to and I wouldn't want you to think that I haven't bothered to reply.
I have ordered a Birth Certificate for my GF Frederick Liffen (b 1894) and agree that the Mothers' surname should be very helpful. Will of course post on here as soon as it arrives.
A slight correction to their address in the 1901 Census, they lived at 7, Edward House, Potier Place (later renamed Rephiderm St in 1905). I understand that GF Fredericks brother George lived in this road too.
I too agree that the age details on various Census forms are making the research more difficult and i wonder why the details my relatives gave varied so much?
Frederick and Adelaide did indeed live at 76 Barnham St Dwellings and Frederick my GF, Mary(Law his wife) and my dad Harry, aunt Mary, uncle Fred and i think Uncle George lived at 179. They later lived at 20 Avondale Sq, Old Kent Rd;they lived there whilst my dad was away in the 2nd WW and he returned there in 1946. In 1952 GM Mary, Harry (my dad),Mary (aunt), and uncle George lived there until 1956(at least). My uncle Fred, the oldest child had left the residence previously (in fact living at 29 Warren Buildings Brandon St in 1945 and from 1948-1951 at 2 Townsend St Old Kent Rd).
Something I've learnt is that the family moved from lodging to lodging but in a very small radius of a mile or 2-likewise my Mothers side were similar-maybe getting evicted or hopefully "improving" their accommodation.
Lizdb-The death in June 1951 is certainly my GF and assume that the other Frederick you mention who died in 1938 is his father, but sadly no one in the family knows.
Your details of 1939, 9 New Kent Rd are proving a little confusing for me (So Many Fredericks !) I believe Uncle Freds first wife was Irene so I can only guess that its my uncle fred, GM Mary or maybe aunt Mary? Maybe not a good idea for me to guess?
I had an Uncle Fred (1917-2005app) who had a son Fred too.
And Uncle did indeed live at 2 Townsend St from 1948-1951. I believe Cousin Fred is alive but we are not in touch .
Thank you to everyonr for your time.
Kind regards
Henry
