William (Liam) Joseph Mellows was an Irish republican and Sinn Féin politician. He was born on May 25, 1892, in England to an English father and Irish mother. His family moved to Dublin, Ireland in 1895 and he was raised in Cork, Dublin, and Wexford. Mellows was active with the Irish Republican Brotherhood and Irish Volunteers, and participated in the Easter Rising in County Galway and the War of Independence. Elected as a Teachta Dála to the First Dáil in 1921, he rejected the Anglo-Irish Treaty. During the Irish Civil War, Mellows was captured by Pro-Treaty forces after the surrender of the Four Courts in June 1922. On December 8, 1922, he was one of four senior IRA men executed by the free state Government. Mellows is buried in Castletown cemetery, County Wexford.
