Old Gravesendians RFC (founded in 1929) consisted traditionally of former Gravesend Grammar School pupils. Prior to the forming of Old Gravesendians RFC, on leaving the Grammar School, former pupils had continued to engage in various sports through the Old Blues Association (founded in 1914). Owing to World War I the Old Blues Association practically went to pieces with only one annual dinner having been held in 1914. After the war a reunion dinner was held in 1920, the second annual dinner, which restarted the Old Blues Association activities. The Old Gravesendians RFC was often referred to as 'Gravesend Old Blues' in match reports.
