Looking for Constant

I have a funeral card for my husbands g father who died in 1922 he was buried in the wandsworth cemetry In the family grave I have been in touch with them and they tell me it is not there I would like to know who is buried with him as his wife died 3 months before him and I don't know where she was buried she was Sarah Ann Constant he was Alfred Constant he died on the 8th of november 1922 . I am in Australia. They were living at 20 bollo bridge road Acton at the time they died. Beryle Mason
