I would proceed with caution though.
As crisane points out, you are dealing with a common name.
Frederick Smith of 37 Falkner Square died in 1936 in a eston, Cheshire. His probate record shows his effects to be very valuable.
After that, records indicate that 37 was flats/rooms.
Your George may not have been related to Frederick.
Electoral registers were not published during the war, so that hinders your search too.
10, Percy Street also looks to be rooms/flats in 1939/40
