Howard,

As to how d'Angio became Angione, there are at least  two possible explanations.

• The most likely is the French suffix "one" which inflates the value of a word by a thousand.  Hence "mille" become "millione."   [When a double "o" occurs, as in our name, one "o" is dropped.]
• The suffix "one" in Italian means big.  Hence a trumpet [tromba] becomes a trombone.

I prefer the first explanation in that it would be logical for Carlo d'Angio to want his opponents to believe that he had a great number of troops under his command.  [On the other hand, given my present size, perhaps there is something to be said for the other possibility!]

I also learned that in Italian, the last letter of our name is pronounced "ay" as in day.  The rules for Italian vowels follows:

There are five vowels, a, e, i, o and u.

• a as in cat or apple
• e before a single consonant, as ay in day. E before a double consonant, as e in get
• i as ee in feet
• o before a single consonant, as o in cone. O before a double consonant, as o in got
• u oo as in moon.
• Note that e is always pronounced, even at the end of a word. For example, the Italian town Udine is pronounced oo-dee-nay.

In French, however,  the "e" would be silent as it is not accented.  Thus the pronunciation of Angione, as we were instructed, is the French way.

I hope this is responsive.
