There was an Otto Sather in Hills, Minnesota. I don't know his origin, but he could have been from Valdres. He passed away about 30 or 40 years ago. All my great grand parents except my maternal were from Valdres, except when I was growing up I/we never thought of such things. Otto's son has also passed away and he had one daughter who still lives in the area on a farm. I think her married name is Nelson. Perry Lien
