The cemetery didn't open till around 1861 so Ann Bonson won't be there. I can't see a Sarah Alice Hibbert in 1927 but I can see
Sarah Alice Hibbert age 72, Stothes Hall Asylum/28 Pindar Oaks Cottages, buried 13 May 1918, Section Za plot 24.
George Bonson age 52, Old White Bear Hotel Shambles Street, buried 14 May 1873, Section G plot 60.
