Welcome to the forum. We would all be interested in any photos you have of your Bulls Head. The Kellys directories for 1939 and 1940 (the latter one probably covering 1939) both list the licensee of the Smallbrook St Bulls Head as Percy G.S Seward., though it is possible that your grandparents ran it, while Mr Seward held the licence. There seem to be no listings of a William or Ida Wood as licensees in Kellys of that period
