Photo of the O'Leary House
There were actually two small cottages on the O'Leary property. The house fronting DeKoven Street was rented to the McLaughlin family. The O'Learys lived in the rear building.
The O'Learys sold their property in 1879 to Anton Kolar and his wife. They tore down these buildings and built a two-story house on the land. The house was eventually demolished in 1955. Ironically, the Chicago Fire Academy now stands on the O'Leary property. On the first floor of this academy, down a hallway, a maltese cross is painted on the floor. It is said that this cross marks the actual location of the O'Leary barn.
