I have been looking for connections to my father-in-law's family from Monacilioni. His name was Giovanni Evangelista and came to Boston pre 1905 with some Iosue cousins, I understand.His father Francesco died in Jersey City and some Iosues are in the counsel's document sent back to Italy.
The Evangelistas came from nearby Toro to Monacilioni in early 1800s. Pa's mother was Filomena Iosue who later married Giovanni Di Santo. Pa came to St. Paul where there were many of the names you mention--Naimo (Nemo), Pillarella, Pietracatella, Narducci, Martino all from Monacilioni.
When we were married my wife & I leased Joe Pillarella's apt. when he went back to Italy for six months. Garabaldi Iosue (Pa's cousin) came to St. Paul and changed the name to Yoswa. Lots of the other names are familar in Pa's family tree. Would like exchange information if any of this strikes a chord.
