John and Mary Konecny- Other trees have her maiden name as Steamy but I can not find anything to verify this. In the 1860 census, John said he was 60, therefore born around 1800 and Mary about 1815. They immigrated to Johnson county, Iowa.
Vader Janes and Marie Asanad- I know nothing of them except that they had a daughter named Helen born Mar 1857.
Josef Hakle and Minnie Vondra- I have seen Hakle spelt many different ways, this is just how it was spelt on his son's death record (Josef Hakle Jr born 1 Aug 1841 in Bohemia).
Frantisek Jasa and Anna Navratil- Franz was born May 1828, Anna in Apr of the same year. They came to America in 1879 on the Suevia, on the departure list their last residence was listed as Neustadtl, Mähren though other records have them born in Bohemia. Franz and Anna lived in Linn county, Iowa.
