I know the OP is not around, but I'd like to register my findings regarding the posts about Mary Stratford (Gerrard) and her daughter Charlotte Stratford (Gerrard).
According to the West Surrey Family History Society website, both died (or were interred) at Lambeth, St. Philip, on the same day, 16 Aug 1875, under the surname STRATFORD. I've sent them an email requesting more information, but the person responsible is on hols until early April.
Georgina Stratford Gerrard was buried at the Bagshot Burial Ground, St. Anne's Church, in 1904.
