Hello Ron. A few years ago, I visited BRNO and the places mentioned in this earlier post. Although I don't have a lot of new information, I do know that several members of the extended Korycansky family (including my gr-grandmother) immigrated from Tasov in the Hodonin district of Moravia in the early 1900s to the eastern USA. There is some mention of this on the town's local webpage.
The USAF major you mentioned was my grandmother's 1st cousin, MAJ. George Cyril Korycansky, so there must be a connection. If you still have Anna Pribyl's wedding photo from 1925, that would be great to see. Thanks.
