Plunkett, Saint Oliver (1625-1681), was Roman Catholic archbishop of Armagh and primate of Ireland from 1669 until his death. Plunkett, like many other Roman Catholics in England and Ireland, was severely persecuted during the Popish Plot, and, in 1678, was arrested on a charge of treason. On July 11, 1681, he was hanged, drawn, and quartered at Tyburn. The Roman Catholic Church beatified him in 1920. He was canonized (declared a saint) in 1975 (see Canonization ). Plunkett was born on Nov. 1, 1625, in County Meath, Ireland, and educated in Rome. His family name is also spelled Plunket. See also Popish Plot .
