Elizabeth,
I haven't established any link yet to your father Brian. This is what I have found so far, if it's of any use!
My grandfathers first name was not actually George as per my previous message. He was always known as George, but this was actually his middle name, his first name being Abraham. He was born in 1920 and the birth was registered in Birkenhead.
His fathers name was Abraham (father George Pumford) and his mothers name Margaret Wilson (father Jospeh Wilson). They were married 25th Dec 1911 in Liverpool.
On Abraham and Margarets marriage cert. it says that Abraham is 21, however I can't find any index for a birth between 1889-1890. The nearest one is a birth of an Abraham in Birkenhead in 1893 so I think he may have lied about his age to get married, as you had to have parental consent under the age of 21 back then.
If this Abraham of 1893 is correct (I have the cert.on its' way) then according to the 1901 census, his father George was born in Shropshire, his mothers name was Eliza or Elizabeth - born in Paisley, Scotland - and he had 4 brothers, David, George, Joseph and Frank.
If any of this ties back in any way to what you have found, it would be great to hear about it.
Thanks
Natalie
