I have a distant branch of DiBella's/Di Bellas in my family tree. My family originally came from Tusa, province of Messina, Sicily, which is close to Cefalu and Castelbuono.
My 5th great grandfather was Nicolo/Nicola Di Bella, married to Anna La Lima. Their daughter, Grazia di Bella, would have been my 4th great-grandmother, and she married Vincenzo Di Gangi.
I realize that this does not provide much information. If anyone is a descendant of this family, I would love to hear from you. My father's parents emigrated in 1901 and 1902 and settled in Westerly, RI, and then in New London, CT. Their surnames were Di Gangi and Di Maggio.
