a fellow member at the Stonehouse History Group found a reference in a census to a senior employee of the Railway Company who lived in a house called "Motor View" in that street. At that time, before cars, there was a regular railcar - a loco and a carriage - where the loco was referred to as the motor.
I assume when cars became relatively common it would have been infra-dig to live in a car!
And from my modern viewpoint - why would I have chosen motor as the word? Didn't strike me!
Looking at the photo, this is probably seals the issue. More mundane than my hopes, but just as interesting.
The project had a "Social History" dimension, after all.

case dismissed!

PS this all came out in a 10 minute presentation to the Group, another was "Noahs Ark Cottage" which a listener confirmed was very much in the flood plain, and it floods. Victorian mores didn't prevent individual humour at least. The image is fuzzy due to distance and courtesy - pointing cameras near windows is - er - um - sensitive.
