Hello Nell,
I have some information about the Rosaria Cacciacarro...her brother Saverio was my maternal great-grandmother Teresa Menecola's third husband. In addition, Rosaria's sister Maria Rosa Cacciacarro was married to Giuseppi Rinaldi. Giuseppi was a brother to my paternal great grandfather Pietro this making him my great-uncle and Maria Rosa my great-aunt.
If you would like to view my tree let me know.
