My ancestors emigrated from the CR in the 1860s and 1870s to the US. Their family names include Kostner, Dusek, Lang, Tittlebach, Houska, Hruby, and possibly Hepkar. I seem to recall, but now can't locate, a mention of a national registry of names. Does such a registry exist, and would it be comprehensible to someone who does not understand the Czech language? Also, I've recently been informed that the 1st generation emigrant son returned to the CR to attend the University where he studied dentistry. This would have been in about 1900. What university could this have been, and would the university have records of enrollment from this time period? I am going to be visiting Prague in a few weeks and could follow up on leads if it seems worthwhile. Thanks for any help.
