came accross your discussions through googling fysher Negus - wondering if anyone had got anymore info on him
My links are Fysher Phillips Negus was my Great Great Great Grandfather born 25 May 1920 so the christening date of yours falls in line. His parents were Fysher Colman Negus and Elizabeth Phillips. As far as I can see this couple were never married. The will & testament of Fysher Colman Negus gives bequests to Elizabeth Phillips " the natural mother of his son Fysher Phillips Negus.
I am not aware of any other siblings for him through either parent
If anyone has found out anymore I would be interested
