From what I have been able to gather, my great-grandmother, Rosa Belmonte, would have been born between 1865-1875. She married Pasquale Marchese in mid 1890's. I have been told that Rosa was born in Rende, Cosenza, Italy.
In that area of Italy, there are families with Spanish last names. From my home town a prevalent spanish surname is Fernandez. No-one in my family has ever talked about any Spanish connection. Perhaps, since it was so long ago, no-one remembers.
