I also am trying to find some information. I have only been able to track some of my information. My Great-Grandfather was Frank Simper who died June 29 1928 in Iowa, born Nov 23 1875 in Austria. He was married to Anne T. Spengler, born 9-16-1881, died 1-19-1953.
Frank Simper's father was Franz Simper of Austria.
If anyone has any other info, please feel free to e-mail me.
