I came across your posting on Genealogy.com from May 2006 regarding the Brossi MACALUSO family of Chicago. My relative, Loretta PRENDERGAST, was married to Brossi. Unfortunately, I do not have anything on the family after that 1968 time frame.
While I have not located anything definite on Loretta,I suspect that she may have remarried after Brossi's death. I did find the following record in the SSDI for a Loretta with the same birth date from Chicago with the THOMAS surname.
Social Security Death Index
Name: Loretta Thomas SSN: 347-03-4201 Last Residence: 60655 Chicago, Cook, Illinois, United States of America Born: 31 Jul 1916 Died: 20 Sep 1989 State (Year) SSN issued: Illinois (Before 1951)
I am not sure if this the same Loretta but I suspect it might be.
I did not know if you were related to the family or a friend. If you are interested in any information on Loretta's ancestry, I am glad to share what I have. Thank you.
