If your Italian Ancestor naturalized before July 1, 1912, you do not qualify for Italian citizenship even if his or her child was born before this individual naturalized. Prior to that date, when a native-born Italian naturalized in another country, he gave up not only his own Italian citizenship but also that of all of his minor children, regardless of where they were born. Ancestors who naturalized before July 1, 1912 cannot pass on Italian citizenship under Italian Law No. 555 of July 23, 1912.
