Hi, I am a granddaughter of Ingeborg (Lindbo) Olson who lived in northern MN. Marna Dahl was my first cousin. My husband, Clarence, is a retired engineer. We and our three married children also live in Billings. I'd like to begin updating our Slektsbok which your father and Marna worked on. We'd enjoy hearing from you. Distant cousin, Yvonne
