Craig,
I don't know whether Oxhey Hall was the same as Oxhey GC. But Oxhey GC was a near neighbour of Sandy Lodge near Watford. It was forcibly closed just after the Second World War and turned into a housing estate.
Here is an extract from my notes concerning the Sandy Lodge Centenary. James Francis Markes was the autocratic founder, chairman and 'everything' at Sandy Lodge:
There was a further need for the club to increase its membership after the war. An opportunity soon presented itself when it was announced that Oxhey Golf Club was to be closed down on October 31st, 1946. Their land was requisitioned to become a housing estate. There was a friendship between Sandy Lodge and Oxhey, but when the Oxhey captain RE Seaton called on Markes telling him of the decision to close, Markes displayed his superior manner. Seaton explained that he could personally recommend members who might be suitable to apply for membership. He asked whether the Sandy Lodge committee might be prepared to elect en bloc 20 to 25 of them. Markes said that this was unlikely as every application to Sandy Lodge had always been considered individually. In practice Markes always interviewed prospective members himself. An opportunity was therefore lost to obtain a substantial number of new members quickly. Seaton understood this and requested that his name should nevertheless go forward to the committee as a candidate. As a co-liquidator of Oxhey Golf Club Seaton approached Sandy Lodge offering a cup and some autographed photographs of Open and Amateur Champions. The cup would be presented on the condition that it be called the Oxhey Cup but it was left to the committee to decide for what it should be played annually. It was decided that the cup should be played for in the autumn meeting.
