Hello,
This is very interesting indeed, I have not started researching my fathers family yet, as I have been doing my mothers first. However I have been hearing so much about this surname as I came across my grandfathers name which was Bartolo Suarez Carattini from Cuyon a barrio of Aibonito. There is much talk there about the Carattinis. If you know of these people and their stories, please post.
Thanks Sandra
