Mullin Avenue is named for George Harry Mullin, who for many years was Saskatchewan's only resident holding the Victoria Cross. He enlisted in the First World War in 1914 and joined the Princess Patricia's Canadian Light Infantry early the following year. He was awarded the Military Medal for his part in the fighting at Vimy Ridge. Promoted to sergeant, he was awarded the Victoria Cross for his action at Passchendaele in 1917, when he rushed a German pillbox that was holding up the advance of the Princess Patricia's, an act which saved many lives. He has been hailed as one of the greatest Canadian front line soldiers.
