To day many people whose last name is Dardis live in San Marco Argentano (Cosenza) in south Italy. Some of them are
migrated to North Italy. May be the original name was D'Ardis whose origin somebody says is from Albany. In the 16th century many people migrated from that country in south Italy and in Cosenza's lands by turkey persecution. The people that I know are Marco, Giovanni, Vincenzo and many other ones. Marco Dardis told to me that an ancestor of his family was named Angelo, but I'm not sure about this new.
