A daughter, Miss Agnes Irwin Mahon, now resides in Carlisle, and was a recent visitor in Pittsburgh. We have Mahon avenue on the 'Hill' named for the family. The Mahon mansion, long the residence of Alexander H. Miller, was on the elevation on Center avenue opposite Erin street. It was razed within the last decade. The Irwin family owned several blocks of land on the opposite side of the street, as old plans and deeds show."
1925-03-08: Source:Fleming-minersville: "John D. Mahon was one of Pittsburgh's leading attorneys from the time of his arrival in the city. Like many subsequent Pittsburgh people of prominence, he hailed from Carlisle, Pa. His old mansion was on the terrace on Center avenue, opposite Erin street. About 1866, the Mahon homestead and grounds became the property of the late Alexander H. Miller, also an attorney. The old mansion was razed a few years ago. In Harris' Directory of 1837, after Attorney Mahon's name is the statement, 'dwelling house, Erin Hill.'"
