Charles Jeffreys was a New Zealander, who worked in a coal mine on the South Island. In 1900, he volunteered to fight for Britain in the Second Boer War. As a private he served for the 3rd Contingent, the so-called Rough Riders. After one year in South Africa he returned to New Zealand. He took up work in a coalmine again, but volunteered again in 1902 and served as a sergeant-major in the 10th contingent. When the war ended shortly after his arrival, he started working in a gold mine and joined the Transvaal volunteers. When the Zulu Rebellion broke out in Natal in 1906, Jeffreys was lieutenant in the Transvaal detachment helping to suppress the uprising. Later he showed indications of a lung disease caused by the quartz inhaled in the gold mine. He then started farming in the Orange Free State. In South Africa, he married Ada Mary Howitt and their daughter Ruth was born in 1916, just one year before Jeffrey’s untimely death. No further information other than of his Olympic appearance is available about his career as a sports shooter.
