I know of Harts in Longhope/ Blaisdon. Rueben was killed in Gallipolli and married Evelyn. They had sons Victor, Horace, Wally, Reg and Benjamin who died as an infant. Rueben was in the Gloucest Regiment- Colour Sgt. His father was David of Hinders Lane Longhope. I have a copy of their wedding photo with his sister as bridesmaid. Very Edwardian with cake frill hats taken in what appears to be an orchard. This may be a branch of the same family as it is not far from Bullo.
