register of emigrated Czech

[jika1303]

"Hello,
Many Czech from Moravia and Bohemia lived in Slavonia (Croatia) between 1820 and 1900. They were mainly near Daruvar and Osijek. In our days, there is an association of Czech descendant in Daruvar.
Other Czech left their country for USA or other European countries. During the First World War, in the Foreign Legion, there was a Czech regiment ( the first company of the 2d regiment of marche, from the first foreign regiment : Nazdar company). Nearby my home, there is a war memorial of Czech who died in France during 14-18.
My question is :
Are-there some register on internet, of emigrated Czech in Croatia, France or other countries ?
Thank you."
