Anthony,
I realize this post is quite old, but wanted to reply in case you are still interested. My grandmother was Grace Ricciardi. Her mother was Caterina LoIacono (1862-1924). Caterina's parents were Filippo LoIacano and Caterina Schiro. Filippo's father was Dr. Nicolo LoIacono (b. 1800)and his grandfather was Giuseppi LoIacono. They all lived in Contessa Entolina, Sicilia.
It is possible that my great grandmother Caterina (Catherine) LoIacano Ricciardi is the sister of your great grandfather Anthony LoIacono. Caterina immigrated to Los Angeles with her husband and children in 1910. I remember hearing about a New Orleans connection.
