Herzan-Kriklava Bohemia (Minnesota) Research

I am looking for any info on my gr grandparents Charles and Anna (Kriklava) Herzan. I have recently been offered the opportunity to travel to Hungary, Slovakia, Austria, Germany and the Czech Republic this April. I have stepped up my search in hopes of being able to at least narrow down where in Bohemia they may have originated. I have a public tree on Ancestry.com (Herzan-Kriklava Family Tree).

Most of the info below I got from the O’Harrah Family Tree. I cannot find anything defining what exactly the Austrian-Hungarian Monarchy is?? Any help or suggestions would be GREATLY appreciated. Thank you – Cindy
