I have Capaldi family from Filignano and Pozzilli. Pozzilli is near Frozinone. It seems that the region of origin of Capaldi is the region of San Biaggio Saracinisco in particular the village of San Giuseppe. In any case, it is what assert genealogists. I was able to go back up until approximately 1750 but there are gaps in my family tree. On a site, I was able to see that the Capaldi patronymic would derive from Gabualdus, a name of Lombard origin. The Lombard would have come from Sweden to Italy during the Middle Ages. If you have infos I would like hear from You.
