I'm stuck figuring out my dad's side of the family. I know his parents were volga germans that came to the US when they were young. They were Henry Lapp, b. 1896 in Frank d. 1963 in Wyoming, and Katherine Hoffman b. 1903 in Frank, d. 1990 in CO. Henry's parents are where I dead end. I know his father was John Lapp, b. around 1885 in Russia. I've found lots of conflicting names for the mother. Anna Maria Lapp, Elizabeth Kroll, Anna Lutz....? Any help?
