I was also looking in the Pescara area for relatives. My husband family is from Torre De Passeri and his uncle Ettore (Arthur)Mariano/Mariani m. Anna D'Intino (all our records were spelled D'Into or Dentino). After finding the new spelling I found her coming over via Ellis Island and they have about 100 records for D'Intino coming mostly from the Abruzzi area. As you can see from Mariano/i we also have a spelling trouble spot.
Hope this helps.
