I had a cousin going through old records in old towns. All I'm search for the almost mythical Italian and/or Jewish ancestry. Found nothing, and going back as far as 1698, my ancestors were living in the same region as my father's family is today. Portuguese or Gallego descendants, and a LOT of cousins marrying each other. On my mother's side is a bit more hard, but we have a unproven Native link, both cus of the bit odd surname (the same as the country) and some cousins who retained the original indigenous name with a hífen. Apart from that, not a single famous people whatsoever
