Pg. 215 – brief genealogy REV. THOMAS M'CULLAGH
To REV. THOMAS M'CULLAGH belongs the honor of having been the first priest ordained in and for the diocese of Pittsburgh.He accompanied Bishop O'Connor from Maynooth College, Ireland, when he came to Pittsburgh at the end of 1843, after his consecration.From the work “Reminiscences of the Rev. Thomas M'Cullagh, of the Diocese of Pittsburgh, by Rev. T. Mullen, we learn that FATHER M'CULLAGH was born at Cranag, parish of the Upper (pg. 216) Badony, County Tyrone, Ireland, in the latter part of October, 1819.His parents belonged to the middle class...(picture of him on this page) Coming to Pittsburghwith its new bishop he was ordained to the sacred ministry at the cathedral, Feb. 4th, 1844...(pg. 217)His health, never robust, soon began to give way under the heavy burden imposed on him, and at the end of a year he was forced to withdraw, going to St. Xavier's Academy, Westmoreland County, where, besides acting as chaplain to the Sisters and their pupils, he also ministered to the small congregation at Greensburg...
In the summer of 1856 FATHER M'CULLAGH was transferred to St. Patrick's Church, Pittsburgh, exchanging places with Father Garland; but on the completion of St. Patrick's Church, and its dedication August 15, 1858, the two pastors returned to their respective places.His health began to decline, and he retired to the Mercy Hospital, Pittsburgh, where the general debility from which he had suffered for the last two years culminated in congestion of the brain; when, fortified with the last sacred rites of the Church, he closed his laborious life in the (pg. 218) evening of June 20, 1859, in the 39th year of his age and the 16th of his priesthood.His remains were taken for interment to the Summit, where some years after a tasteful monument was erected to mark the spot.
