I am fairly shaking with excitement! I have been in touch with the Winchester Records Office and discovered more about Albert and his family.
His parents were both born in Bishopstoke, Charles Henry Foster in 1843 and Elizabeth Ann Macklin in 1844. They were married in Southampton in September 1861. The had 9 children as follows : Frederick Herbert (1862), Alice Amelia (1865), Helena (1867), William Henry (1871) - my great grandfather, Harry (1873), Alfred (1875), Rosa Frances (1877), Albert (1879) and Edwin (1881).
What was your great grandfather's name, Richard?
I'm still searching so I may have more news later!
