A quick google search on 14 St George's St, Douglas reveals that is currently a Company operating out of 18 St. George's Street, so yes there would have been a 14 St. Georges Street in 1940. It is (believe it or not) near St George's Church in the heart of Douglas. Douglas, many many years ago was a town within the parish of Onchan, but ceased to be once it became a 'Borough'.
