My grandmother and her sister were place in St. Vincents on May 7, 1923. I called Center For Family Services, Records and Archives, 11 East Mount Royal Avenue, 2nd Floor, Baltimore, MD 21202-2753 phone: 410-685-2363, fax: 410-685-2364. Mrs. Helen Graham (Director of Records and Archivist) sent me all the information she had. They kept all the records from St. Vincent's. I also got the certificate of Baptism. Unfortunately for me the birth mother DID NOT list the father's name.
I hope this helps you out.
