Born in 1857 at Wellbank, Sandbach, Cheshire, he was the youngest son of Joseph St. John Yates, County Court Judge & his wife Emily Augusta Scott. His father was a descendant of Sir Joseph Yates (1722–1770) and his wife Elizabeth Baldwyn. He was educated at Shrewsbury School and Trinity College, Cambridge. He was called to the bar to the Inner Temple in 1881.
