Drevo/Kasha/Shara/Kubicek

Looking for help in researching the following lines, especially immigration and Bohemia information:

Drevo (from village: Slapy, near Tabor) , Kubicek (from village:Nezamyslice, town: Susice, county:Pisek) , Shara (Sara) (village: Bechlin, town: Roudnice), and Kasha (Kasa) (no information)

I have Drevo and Kubicek records for immigration but none on Kasha/Shara. I think they may have come over to the US around 1855. After being in Kossuth, Manitowoc WI for awhile, the Kasha/Shara line settled in Cuba, KS. The Drevo/Kubicek families settled in Saline Co. Nebraska.
Any information on these lines is greatly welcomed!

Thanks,

Cammi Drevo-Amezcua
