Jeez. That's much worse than my situation. First, my mother misspelled her maiden name on my birth record.

Then, my dad gave up his Italian citizenship before going back home to visit in the 70s, so that he wouldn't get stuck doing a year of military service. Also, according to Canada, he was born in Jamaica, not Italy (wtf?). And even though we figured most of this stuff out, when my sis took the documents to the Italian consulate in Edmonton, the guy there (Ambrosino) told her "there was a problem that year" in regard to the year I was born. lol.
There are strange rules to this. My dad was born in Italy, and came here when he was 10. He did not apply for citizenship until he was 30-something, and only did because he married my mother and wanted to take her to Italy on a trip. Because he married her while he was Italian, she "became" Italian. However, once he gave up his Italian citizenship (which was the year
before I was born), I was no longer eligible to get Italian citizenship through him, but, (loophole), now my mother is "Italian", so I can get it through her, even though they've been divorced for over 30 years. Except for that pesky part about "there was a problem that year".
Never change, Italy. Never lose your mystique. Nobody knows what the problem was that year, but there
was a problem that year.
