Hi May,
I'm Colin Jaccino, the first son of Gretchen Vandewater via the Jaccino line.
Moschetti is Margherite's ( or Margherita's) maiden name. She and Rocco Iaccino married on Dec 13, 1897. Margherita claimed to come from Palena, Italy, which is in Chieti, Abruzzo, Italy. Rocco, according to memory, came from Celico, Cosenza, Calabria, Italy.
The two are the biggest mystery of the family try currently, as we haven't found a clear line to trace back to Italian ancestry. Feel free to contact me - (cjaccino at gmail.com) and we can share more.
