Ringsaker Parish

Members of my family emigrated to the USA from the Botsender region on Lake Mjosja. They were from the farms of Hvalstad or Kvalstad, Hoel, Berg and Aanarud. They took the names of Hvalstad later Walstad, Hall and Berg. My great grandfather was Lars Thoresen (he took the name Lars Hvalstad) and my great great grandfather was Thore Andersen. They both emigrated to the USA, I am curious if any of our line of kin still exist in Norway.
