I'm trying to find information on my ancestors. My great-great-grandfather, Josef Trutna came to Nebraska in May 1875, from Gerschdorf in Moravia. His wife was Frances Pestal (Pestalova). First wife's name was Palasova Frantiska. The Korista's came Silver Lake Minnesota from Nalisna, Moravia in 1874. Any information would be helpful. Thank-you.
