Thank you for your reply. The names do not ring a bell, but it is interesting that your grandparents are from Palermo.
I would think that there is a connection. But, it would have to be a distant connection as I am sure that all of my grandfather's brothers and sisters came to Florida or stayed in Palermo. He probably had cousins who moved to other parts of the country. I don't ever remember anything being said about about any one other than his siblings.
I will let you know if I come upon other information that shows any kind of a connection. Please let me know if you come up with new info.
