No, my Uncle John (Giovanni) never left Italy. He was born in 1900, my father's oldest brother and never married. I think that the John you are talking about is the one that came to visit my dad too. He lived in Queens, NY. He was the son of Tommaso Isabella, hence my dad's and your grandfather's first cousin. I remember that when this John Isabella visited, he had a picture of his dad, Tommaso, and he looked just like my grandfather and my dad!
