My Czech family name is Bures. I know in the Czech spelling of the name the is a divet thingie on top of the 's'. My grandfather was very adamant about the pronunciation of the name. His pronunciation was: Byur-es When a Czech person pronounces the name, they say: Boo-resh (with a nice curl of the 'r') My grandfather said that under no circumstances should I ever pronounce it any other way than his way. I am wondering why? Was there some shift in Czech dialect at one time? Is it a Czech/Slovak difference? Or could it just be the Americanization of the pronounciation? Anyone know? I have been curious about this for a very long time.
