Brought up in rural County Leitrim, he was a member of many associations which promoted the cause of the Irish language, Gaelic revival and Irish nationalism in general, including the Gaelic League and (early in his career) the Irish Catholic fraternity the Ancient Order of Hibernians. He was the national organiser for Sinn Féin, and later manager of the newspaper ''Irish Freedom'', started in 1910 by Bulmer Hobson and others. Provided by Wikipedia
