Houser/Kopulety

I’m trying to find out where in The Czech Republic my fam came from. Josef Houser B. 20,mar 1845 and his wife Frantiska Kopulety B. 19, July 1843, children Cyril 13, Josefa 11, Jan 10, Peter 6. They came to the US in Aug. 01,1892 on the ship Weimar, sailing from Bremerhaven. Place of residence Komsen, Austria. I have everything on the family here in the states. I’m having a hard time trying to find them in the Czech Republic. I believe they came near Trebic, a small town of Konesin, Movera. I found a history of the Town Deep, in which I see these names, Houser, Kopulety, Svododa and Budin. All family names. I need to find the czech census of that area. would appreciate any help
