I'm not sure if this is going to be of much help to you, but I think my Great-grandfather may be related to your Antonio. Dominic Annacone arrived here in 1902 with his wife (Christina Cannonica) and my grandfather Thomas Annacone on the ship Paldino di Francia on January 5, 1903, in the Port of New York. My grandfather's birthplace was Montforte, Arpino. My branch of the Annacone family (they dropped the I when they arrived here) settled in Peekskill, NY, although we know there are other Annacones further up the Hudson River (near Poughkeepsie). Hope this is of some help; feel free to contact me directly if I can be of any further assistance.
