You're right they went to America before 1907. Rocco Di Francescantonio was born on 29 feb 1876 and married Adelina Iavicoli born on 14 feb 1877. In San Vito there are many families "Di Francescantonio" but not your branch. There are living descendants belonging to Andrea Di Francescantonio (1874-1958), one of Rocco's cousins.
Merry Christmas
