Hi
The best way is to work backward from your parents and grandparents, using censuses and certificates to confirm parents.
You are lucky with a name like that, there appears to be only one in the censuses. In 1881 Harry Tempest Bentley is with him, so it is the correct man. Piece: 4771 Folio: 32 Page: 10
