I've looked at Wolverley on an 1888 Ordnance Survey map and found what might, just might be "Wolverley Boat" - the word "Boat" is difficult to make out. Might just be seeing what I want to see!!
Close by on the map is "Wire Mill" and "Wire Mill" appears on the Census image following the "Hickman, The Boat" Census image.
