I am the great grandaughter of Peter Fredrick Balle Hoem Krohn,. I believe he was adopted and am trying to locate his real parents. His son, Rolf, was my great grandfather who immigrated to the US in 1905 after his father died and ended up in Consort, Alta. I know very little about the Krohn family and wish to learn more. What is the title of the book about the Krohn's, Schanche's, etc, who is the author, and where would I find this?
