Peter,
I have knocked a big hole in your brick wall and traced your Bradbury family back through several generations. Your grandfather's full name was Albert Percy Victor Bradbury. He used all three of his christian names on censuses etc. Albert P.V.Bradbury was born at Sheffield in Mar Qtr. of 1880 to William Mark Bradbury. Contact me and I will let you have full details. My email address is

John Bradbury
