Biography Cronin was born in Dublin but spent his childhood years in Ballinskelligs, in the County Kerry Gaeltacht.
During the Second World War, Cronin was an officer in the Southern Command in the Irish Defence Forces. He later emigrated to New York City, where he found work as a journalist. In America, he became involved with Clan na Gael and later joined the Irish Republican Army.
