Charles was educated at Belvedere College, Dublin, qualifying L.R.C.P. and S.I. in 1905. He had a good reputation as a sportsman, and although having a strong record at rugby while he attended Belvedere his greatest talent was as a horseman, became well known as a talented jockey, he was regarded as one of the best amateurs in Ireland at the time. In 1907 he was on top of the list of winning amateur jockeys. On the 29th July 1907, Charles gained a commission at the rank of Lieutenant in the Medical Services. He started service in India in 1909, and was successful as a jockey there too. He was promoted to Captain on the 29th January 1911, then returned to Ireland in 1913. The following season was a successful one for him - winning thirteen rides from twenty-five mounts. Charles was stationed in Kildare when war was declared. He went to France in August 1914 as the Medical Officer of the 5th Bn. Royal Irish Lancers. He is said to have treated Prince Max of Hesse for serious injuries. Prince Max was a relation of the Kaiser. For his help, the prince awarded Paget a gold watch. He was killed by shell-fire whilst crossing an open space to assist a wounded comrade. After the war the gold watch was returned by the O’Brien-Butler family to the House of Hesse. Charles came from a family of military service and sport. His brother Pierce, a more talented and successful rugby player, died in South Africa in the Boer War. His younger brother Capel was also killed in action in the war, in 1917, and his father, Pierce, was a Major in the British army who served with the 60th Rifles. Charles was the husband of Winifred Mary.
