Regarding pronunciation of Aloysius, ... when my wife and I travel to my family reunion in Alabama, she attends mass at St. Aloysius church in Bessemer. The (Irish) priest pronounces it like Aloe - ish- us with emphasis on "ish." Here in New Orleans there is a St. Aloysius school and they pronounce it the same way. So if Irishmen and Cajuns pronounce it the same way, there has to be a reason.
If you want to see some crazy names, can't beat south Louisiana. Though in these cases some of the pronunciations might be regionalisms. Here are a couple for you:
Yscloscky - the name of a small community down-river from New Orleans. Your first guess is probably going to be wrong.
Ouachita - the name of one of our parishes (counties to everyone else)
Tchopitoulas - the name of one of our streets in the uptown area of the city.
Nachitoches - a small town on USA Interstate 49 between Lafayette, LA and Shreveport, LA. Not to be confused with Nacodoches, TX.
Hint: Three of them are Native American words or proper names that were transliterated by French explorers.
Colin, the #1 item from #22 ought to be "bat" - which will give a lot of "hits." Didn't have to look that one up.
The #2 item is the proper name for a contest or challenge to find some two-word item that returns exactly one response.
