I'm not related to anyone called Pybus but FYI there are 2 soldiers named Pybus listed at our war memorial gardens in Cottingham East Yorkshire (died in WWI). There was also a man called Pybus who ran a small clothes shop in Hallgate near St Mary's church in Cottingham. My mum used to go there for my school uniform (circa 1968-1970). I'm sure the old man (Walter?) had since died.
