Feroleto Antico is about a mile away from Pianopoli, where my paternal grandparents were born!My Fazio family is very likely related to yours. I don't have any concrete evidence though at this time. I am corresponding with several people at this moment trying to learn more about my Pianopoli connections.
A few questions for you:
1) Is Rosaria a family name in your family? Any aunts or cousins with that name?
2) Traditionally in Italian families, the eldest son in a family was named after his paternal grandfather, and the second son was named after his maternal grandfather. Do you know the given names of your great-uncles?
3) There were Donatos from Pianopoli or thereabouts who settled in Rochester, NY, where I live.Are you related to them?
