The 555 serves the Coneygre area of Filton.
Coneygre? There's one in Tipton (West Midlands); there's a Conygre Farm near Hoveringham in Nottinghamshire. There are also plenty of Coneygrees and Conyegars. Amazon have no stocks of a book called "The Conygre Story" (and no picture of the cover, either).
So, who, or what is Coneygre?
