Hello,
I'm a bit stuck working backwards from this one. I believe he was born on 20/01/1890 (from later naval records), and appears as a 1 year old in the 1891 census:
Hampshire/Portsea/Kingston/District 49
RG12/860
on the fourth row down, below mum and older sister.
Dad is not on the census, and I don't know his name. I also don't have any details about his parents' marriage or the birth of his older sister Ethel. The census gives his mum's first name as Eliza and a place of birth of Battersea, but I can't find her on any earlier documents.
It's a while since I last looked at this one properly, but I remember various false starts where I found similar couples but then there would always be some inconsistency. If anyone is willing to lend a fresh pair of eyes to it, I'd be glad of a fresh perspective!
Many thanks.
