Well they certainly don't have polish sounding last names. There's no 'von' or 'stein' endings in polish
It is quite amusing what you say and shows how little you know about Poland or about life. The principal name in question is undoubtedly Róża
Gräfin von Thun und Hohenstein. First, her Christian name is RÓŻA, a lovely sounding Polish name. Then she was born in Kraków, a lovely Polish city. And last but not least, she married Franza Graf von Thun und Hohenstein, hence her lovely German surname.
The kind of attention and sort of malicious satisfaction they give to the pronounciation of her German name on the Wiadomości news bulletin, the main speaking tube of government propaganda on TVP1, amuses me enormously and shows how childish people can be at their silly games. It sounds at least as she were one of the
Hochmeisteren of the Teutonic Order which we success fully defeated in the battle of
Grunwald in 1410, such a bombastic pronounciation this is.
