Overview
George Oliver Plunkett (; 5 July 1894 – 21 January 1944), known to his contemporaries as Seoirse Plunkett, was a militant Irish republican. He was sentenced to death with his elder brother Joseph Plunkett and his younger brother John after the 1916 Easter Rising, but while Joseph was executed, George's and John's sentences were commuted. He was released in 1917, fought in the Irish War of Independence and Irish Civil War, and was briefly IRA Chief of Staff during World War II.
Early life
Seoirse was born in 1894, in Dublin, where his parents lived at the time, the son of George Noble Plunkett, a papal count and curator of the National Museum and his wife, Josephine, née Cranny; the Plunkett and Cranny families were both housing developers.
George was named after his father and his collateral ancestor Oliver Plunkett, Archbishop of Armagh, who was martyred in 1681. He was one of seven children; his siblings were Philomena (Mimi, 1886), Joseph (1887), Moya (Maria, 1889), Geraldine (Gerry, 1891), Fiona (1896) and John (Jack, 1897). Like Joseph he was sent to England to be educated at the exclusive Catholic public school Stonyhurst College, where he acquired his upper-class English accent.
