Good Morning,
Ok i had c1869 on my family tree at the start but since looking more in depth the only birth i can find is for Frederick George Stapleton in 1868, the one you refer to. I can find no birth for Frederick George Walker (the name he appears to use later) around that time atall.
The marriage i refer to is of Frederick George Stapleton and Elizabeth L Gravestock in jan qtr 1891 Hemel Hempstead,
The information i received from my nan was that he was Frederick George Walker and she was Elizabeth Louisa Crawley. I can find no marriage record for any combination of these names and so i am fairly certain this is them married using their 'mothers' names, for what reason i cannot be sure.
I did find a probate record for Elizabeth Louise Stapleton Walker when she died in 1942 which giving the Stapleton name gives me great certainty that these are the right people.
William (Walter Charles) Walker was my nans father. The names Walter Charles would be significant aswell i believe, Charles being Fred's father and Walter, Elizabeths.
When i refer to Charles as his father, this is where my incertainty is. because although he knew him as his father the date of their marriage being 3 yrs later and the name of his birth being his mothers, i wonder why?
Thanks
Sarah
