My grandfather was Alfonso Viscusi and he married Filomena Viscusi (hopefully they were not related).
Hopefully not related?? and from the same town?
My own parents were 4th cousins and didn't know it 8O ... my step-great grandfather was also my great great uncle... one of my great uncles married his niece... my first cousin is also my third, 5th and 7th cousin...
How is your American research coming along? Were you able to research records of your Grandparents (census records, manifests etc.)
