(1764–1841). After serving in the army 1778–91, Sirr settled in Dublin as a wine merchant. In 1796, however, he was appointed town major, in effect chief of police, a post earlier held by his father Joseph Sirr. He thus became one of Dublin Castle's leading agents in the campaign against the United Irish movement in the city. The high points of his career were his apprehension of Lord Edward FitzGerald and later of Robert Emmet. The post of town major disappeared when the Dublin police was reorganized in 1808, but Sirr was permitted to keep the title, and remained in office as an assistant magistrate until his retirement in 1826. In later life he developed a strong interest in Irish language and antiquities.
