I am not sure if this will help. Sadly I know nothing more of the D'Ercole side of that family. I am a descendent of the Ranalli's and am still in touch with many of them.
Iola Ranalli (pronounced Yole) married a man named D'Ercole, and lives still in Scerni. They had a daughter named Elisa and a son, both born in Scerni.
