Hi, I see that this is a very old note but if you happen to see my reply someday, I would like to mention that I am a Caraccioli descendent from San Pedro Sula, Honduras. My grandfather was Leopoldo Caraccioli, who was one of Joaquin Caraccioli s grandchildren, he was a son of Luis. So, my grandfather was one of your father s cousin.
Good luck on your search!
