Finally I have got some more information here in Sweden. This person that I am looking for Erik August Fredriksson, born 1852, in Langtora parish, Uppland, Sweden, did live in South Amalia Douglas County, Neb. I have a letter from him written in Sept 1893. He got an inheritance because his mother died and he received money from Sweden.
He is the brother of my grandmothers grandfather.
I would like to know what happened to him and his family and if any relatives of his today are interested in his Swedish ancestors.
