From family folklore, they said that in looking to improve their quality of life, some of their family and neighbors were leaving Naples, Italy. Some went to Uruguay,to South America, and Africa (can't remember what part). It was even mentioned that my descendants teetered between those countries before finally settling on New York. From there some stayed, some moved to Connecticut, to Florida, and scattering across the country to California.
I would love for a Cuiffo descendant to take a YDNA test...can't beat the price
