Just found a piece of information. St. Vincent DePaul Infant Home (and Orphanage?) in Chicago, Illinois, was located at 721 North LaSalle Street in Chicago. It was closed in 1972 due to a lack of funding and referrals. The records from St. Vincent now reside with Catholic Charities at that same address, 721 North LaSalle Street in Chicago, Illinois. I found this out while doing some genealogical research for a friend of mine.
