I live in Alexandria, Virginia and first heard about Bannockburn when reading a history of Washington Golf and CC in Arlington, so glad to know more about it. I thought Washington Golf, Chevy Chase, and Columbia were the only pre WW1 clubs in the Washington DC area. The Washington Golf history mentions Bannockburn when describing the results of the club's Spring Invitation tournament in 1916. Members from the Metropolitan Club in downtown Washington founded Chevy Chase (initially for hunting) and Washington Golf in the 1890s. Do you know who founded Bannockburn (must be some Scottish link)?
