But you must get the right Preston.
The name, spelt Preston Gubbalds in some historical sources, is derived from the Old English for "priest's settlement" [i.e. Priest Town], along with the name of Godebold or Godbold, a priest who was subtenant of the manor in 1066 and at the time of the Domesday Book survey.
Of course, once upon a time, you could simply ring the man in Preston bus station ...
