Hi Laura,
I will check into this for you and see what I can do. I did find a manifest for a Rosa Coluccio (born about 1870) traveling to Brooklyn with her daughter Maria, (born about 1892) and brother in law Domenico Cimino - she was going to see her husband Giuseppe (Domenico's brother).
Is this the manifest you were talking about?
