Louisa Maud,
She died on 25th February 1870, I believe she is my 3rd Great Grandaunt. I found her on the 1851 Census when she was staying/visiting her brother James John Olive in Hammersmith. She was aged 60 then and born in Brentford, Middlesex.
So that makes her Mary Olive, born in 1791. Her brother James John Olive was born in 1797.
I have not been able to find any other meaningful reference to her and was hoping her death certificate would give me some more clues!
