I have discovered that Gaetano's parents names were Augustino and Alfonsa Gentile Massarella. Gaetano's daughter, Addolorata, married Tomaso Pellicci who was also born in Settefrati. They were my grandparents. Tomaso came over as a teenager, met Addolorata, fought in WW I, and got married in 1922.
I plan to begin writing letters to Settefrati after the holidays and if I learn anything I'll contact you. One of my Pellicci relatives still owns a home in Settefrati even though he was born and raised in NY.
