Not necessarily. I was contacted by someone with my same last name who found me on the Internet, and his family pronounces their last name differently from the way we do. Which is correct - well, they have anglecized the pronunciation name and we use the actual Italian pronunciation.
Strictly speaking, Nederlander is Dutch meaning neither country and the correct pronunciation is NAYderlander which over time seems to have become NEEDerlander.
yea cause i say NEEDerlander, and my friend says NEDerlander, and we always laugh when the other person says it because we've sort of agreed to disagree at the pronunciation. But since I saw this thread I was wondering if there was a 'correct' way to pronounce it.
It is NAYderlander, but they've anglecized it to neederlander. There are a lot of examples of that which are much more striking, especially with Italian names like mine. I had a friend whose last name was pronounced De Bias. If you use the actual Italian pronunciation, it's De BEEAHZAY. De Loosha is actually De Lucheeah. My favorite, though, are names with C - Lecesse - people say luhsessee when it is luhchaysay. In my part of the country, everything is anglecized.
Then you can start on Slavic families in non-slavic countries...
Jane Krakowski? It's just wrong. It should be Jane KrakowskA, pronounced Krak-ov-ska. Her family would be the Krakowscy family (Krak-ov-s-tsy) and so on.
It's natural that these things are anglicised, although, sometimes it's annoying.
