Scholar and Presentation Sister Máire B. de Paor, is one of the latest to try and tell the true story of St. Patrick, the man behind the myth, not to mention the holiday and the parade. With close attention paid to the latest historical research, Sister Declan (as she's known) traces Patrick's life from his capture and enslavement, to his calling as a missionary in "Patrick: The Pilgrim Apostle of Ireland."
