There is a plaque commemorating Farrell on the front of one of his boyhood homes at 5704 S. Indiana (SW corner of 57th and Indiana - from the side of the building looking west, you can see directly to the John Raber house).
Also, Farrell's parish was St. Anselm's, 61st and Michigan, which is still operating as a Catholic church.
