I think it is very possible that no.17 was Thomas Kidman's baker's shop. (It was my first thought).
As you can see, 8 Southfield Road is purely residential so he must have worked from a shop somewhere. The houses on Southfield are lovely and the area looks to be fairly affluent now as it would have been in the 30s.
I wonder if there are any trade directories or newspaper advertisements which may help you find Kidman's bakery and when and where it was? .
First of all the above number of house/building above, should be 89.
Was at the library and got access to Ancestry intending looking for Burial Registers but not knowing my way around it, didn't get anything. Will have to make another visit.
However, don't know how it happened,I ended up with a Street Directory for 1941 giving me 89 Southfield Road, Acton,W4 and there wasThomas R Kidman - Baker.
From what I can make out he was at this address from 1939/1941 - then don't know where he was. The war may have had something to do with.
1949 he was in Finchley, Friern Barnet (he would have been 60 yrs by then and perhaps retired) 1953/1964 he was at 11 Crown Court, Friern, Barnet where he died in 1964.
So I think we can say, he had his own business.
