Williamson - On any censuses?

[Ewan]

Hello

A big thank you to you all for your time spent finding Arthur Williamson on censuses.  LKL thank you for asking about a transcription, at the moment I just needed to know where he was, but if you do happen to look again, if by any chance was there anyone with the surname of Cox from Birmingham nearby.
 
It does look like this family were quite wealthy and it could explain how a telephone exchange business was set up with Arthur c 1880, when he was living in Plymouth for the 1881 census.

If Arthur was in Teddington for the 1891 census, I wonder where he was for the 1901 census.

Can anyone help locate him please for the 1901 census?

Many thanks
Ewan
