From the Brennan House website:
The Brennan House (1868) is a Victorian mansion in downtown Louisville that is filled with an entirely original family collection. Thomas Brennan, a native of Ireland and a prominent inventor of the day, moved into the six-bedroom house with his wife, Anna Bruce, in 1884 and the house remained occupied as late as 1969. Two of the sons became doctors. One of them, Dr. J. A. O. Brennan, added a waiting room, office and examining room as a north wing to the house in 1912. Others moved to New York, including one son who became treasurer of the New York Yankees.
