The Bishops appear to have been quite a large family of mainly agricultural labourers, living at Rousham, Oxfordshire before William Perrin married Sarah Howse in 1770 and still living there after the last Perrin had left.
I have begun inputting BMD data for Catherine W Bishop, who married my G-G-Grandfather William Perrin: her parents, her brothers and sisters and the husband (Charles French) and children of her elder sister, Elizabeth. One of these children was Charles Owen French who became Vicar of Pudsey in Yorkshire around the start of WW1. The eldest child of these children had a curious middle name: Charlotte Agnes Besloh Owen view it. I wonder why?
