Robert, Charles, and George Rooke were born in England and moved with their parents William and Hannah Rooke to Saskatchewan to homestead. Robert Percy Rooke, age twenty-two, enlisted in Winnipeg, Manitoba on February 9, 1900 with the Lord Strathcona's Horse. His brother Charles Winn, age twenty-four, also enlisted on January 9, 1900 with the Lord Stathcona's Horse. Both served in South Africa and returned to Canada early in 1901. They both re-enlisted with the Canadian Mounted Rifles, along with their brother George Cyril, age twenty, who enlisted in December, 1901, and served in South Africa until the end of the war. The original letters have been donated by the family to the National Archives in Ottawa. The collection consists of more than 40 letters written by the brothers to their family back in Canada.
