I've found details of Hugh Leonard William Sixsmith for you, specifically addresses at which he was registered with the GMC:
1939 and 1943 - Pant Glas, Coldbrook Rd, Barry, Glamorgan
1947 - 1959: Lynton, East Lane, West Horsley, Leatherhead, Surrey - and he is listed as having an OBE from 1947 onwards.
So presumably that will give you some idea of where Shelia lived at different times
