HI there,
I was looking up the ancestry of the surname ERRANTE when i read your email about trying to get some answers. Not sure if i can help but lets give this a go. I am from Australia (where we are the only ERRANTE family in Melbourne) but my father's entire family is in Sicily!!
There are heaps and heaps of ERRANTE families there!!
Are you from New York?? I know dad was saying some of his cousins cousins are in America and he is heading back to Sicily after boxing day!!!
I haven't got alot of information- but if you email me what you know i can ask him!! And he can ask while he is there!!
:-)
I truly hope your answers come to you - one way or another
Best wishes
Grace Errante
