This is completely an exercise in futility.
First of all I agree with DMB's assertion that all you dumb rednecks will never get the names correct anyway.
Secondly and more to the point, it must first be determined whether or not we are bound to pronounce words according to the country of origin or "however the hell we want."
Case in point. We (by we I mean us arrogant Mer'cans) generally do what we want with regard to pronunciation.
Here are some examples.
1. Greek Letters - We foul them up plain and simple. Beta is not BATE-uh. It is VEE-Tah. But we say what we want so F those stupid socialist Greeks and their damn letterz. (disclaimer: Wifey is Greek. Real Greek not the "I'm Greek even though I've never been and my dead grandmother is the only person in my family from Greece" kind of Greek. I love Greece and Greek people but they suck in their socialism. Stupid Stupid people)
2. French - Do not even try to pronounce french as the french if you value your manhood. SO GHEY! We all get a pass on that one. FYI, the french do NOT say, "Honh Honh! as you might expect. My people, Cajun People, do a good job of "maculinizing" some French words.
3. Regional pronunciation - Why do the yankees from Illinois say Ellinois and warshing machine and get away with it? ARGH!!! Stupid, stupid yankees.
4. Canadian - They suck, period, eh. That's all I have to say aboot that!
Just about the only thing we get right (don't get me started on why) is Spanish (apparently pronounced Eh-spanich).
The double l "ll" is pronounced with a 'ya' sound. Most Mer'cans get this right.
Ok I'll get started. We get it right because too many Eh-spanich eh-speakers DO NOT learn or care to learn English and there for it is everywhere INCLUDING in government documents. It is shoved down our throats.

(disclaimer: I do not have a problem with hard working immigrants who enter this country legally)
There you have it.
It is up to you if you want to pronounce words as they are in the country of origin or as you wish.
