David Dunbar (14 September 1886 – 7 November 1953) was an Australian film actor. Dunbar was a prominent actor in American and British silent films, particularly in westerns, but switched to playing more minor roles after the arrival of sound. In later years he appeared mostly in British-themed Hollywood films. He was one of the first film actors beginning his screen career with Pathe Freres, Paris in 1910. Previously he was an actor on the legitimate stage both in Australia, his homeland and in Britain. On 7 March 1926 his wife Blanche was killed in a car collision in the Hollywood Hills. He had one sister, Miriam Kathleen (Strachan) Dunbar who remained in Petersham, New South Wales. Miriam married William Thomas Strachan, the children of that marriage being Miriam Kathleen and William James Strachan. William James (Bill) returned from the Second World War to Australia and settled with his wife Barbara (Grant) Strachan in Sydney and later in Melbourne, Victoria, bringing up three children, Susan Marion, William Grant and Scott James Strachan. The Strachan family included Graeme Ronald (Shirley) Strachan, a media personality and lead singer of the 1970s rock group Skyhooks. Miriam Kathleen married Ronald George Fordham, who perished as a prisoner of war in Malaya during the Second World War. Miriam Kathleen died in 1944, leaving Brian Ronald and Joan Fordham.
