The only way to be sure where she was born was by getting the birth certificate, though then it would probably be at home. James & May are shown on the electoral rolls of 1920, 1935 and 1939 as living at 2 Westminster Terrace, Landor St. the map below shows Westminster Terrace houses in red, just to the east of the junction of Landor St and Adderley Road. As the street numbering starts at the east end of the street, I would guess that no 2 would be the second house in on the right hand side.
