for about 8 months now i have been struggling with tracing my relatives

I have spent more than i can remember on ancestry.co.uk and similar trying to trace my family tree
I cannot seem to find a definitive path, either certain details do not tie up or i can find nothing
So confirmed details i have are thus:
Name : Alfred Edwin Edwards
Place : London
DOB: 14/12/1902
Father of Alfred Edwin Edwards
Name: Alfred Edwards
Place : ?
DOB: abt 1882
Father of Alfred Edwards
Name: George Edwards
Place: ?
DOB: ?
Also another enigma is my grandfather Alfred Edwin Edwards had an older sister who was only ever referred to as "Nellie" but we do not know if this is a nickname.
Now i can see on findmypast.com that there is a 1911 census page for Alfred Edwin Edwards born 1902 but i'm guessing there will be no "tie-up" info on there at all

If someone, at there leisure could have a quick look i'd be extremely grateful.
I would sign up for findmypast but in truth i'm running out of money to keep throwing down dead ends
