Do you have his death certificate? If so does it give a place of death (though probably a hospital)
He is hard to pin down in 1901 and variable spellings of his surname do nt help. Any idea if he got married?
Ancestry has London electoral rolls that he might be on but hard to know if its him.
Sometimes if people were in institutions around that time they are only enumerated with their initials.
Hope you solve the mystery
