St. Malachy, whose Gaelic name was Máel Máedóc, was born in Ireland in AD 1094. He became a Catholic priest and later the Archbishop of Armagh. Several miracles have been attributed to him, according to evidence investigated by the Roman Catholic Church. He was the first Irishman to be canonized by the Roman Catholic Church.
Malachy was an influential reformer within Irish Catholicism, bringing its liturgical practices into closer agreement with those of Rome. For his efforts, he was appointed legate for Ireland, but during his second trip to Rome, in 1148, he became ill and died on November 2.
