I`m haveing problems finding any jebb family in london in the 1800s.I need to trace jebbs in the south west area of london in particular.My great granfather was John Henry Jebb and could have been called jack?,he was born 1875 ish and he had brothers frank,george,and sister Lorna.There was a Sir Joshua Jebb who opened a womens prison in Fulham,London,England around 1854.I believe he came from Derby,England.
