Biography
Early life
Anthony O'Regan was born in Lavalleyroe, County Mayo, and studied at Maynooth College in Maynooth, Ireland.
O'Regan was ordained to the priesthood on 29 November 1834 for the Archdiocese of Tuam in Tuam, Ireland, by Archbishop John MacHale. Following his ordination, MacHale appointed O'Regan as professor of scripture, Hebrew language and dogmatic theology at St. Jarlath's College in Tuam. He was named president of the college in 1844.
In 1849, Archbishop Peter Kenrick of the Archdiocese of St. Louis recruited O'Regan to head the newly established theological seminary in Cardondelet, then a village near St. Louis, Missouri. He received his episcopal consecration on 25 July 1854, from Kenrick, with Bishops James Oliver Van de Velde and John Henni serving as co-consecrators, at the Cathedral of St. Louis. He soon began construction on a new episcopal residence, completed in 1856. A crash in the Chicago real estate market in 1857 was another stressor for O'Regan.
Unable to cope with the diocese and in declining health, O'Regan traveled to Rome in 1857 to submit his resignation as bishop of Chicago; Pius IX accepted on 25 June 1858, and named him titular bishop of Dora.
