Searching for info

Hei! I am searching for info about my old uncle, Olaf Kjorstadmoen, born in 1910-1911, Sør-Fron in Gudbrandsdalen. His fathers name was Ole A. Stendalen b.1888. He had 7 sisters and 1 brother: Marit, Karen, Inga, Kari, Olga, Anne, Martha and Erling. Martha b.1925 was my mother, she passed away in 1990. They are all passed away, so all I know about Olaf is that he went to America when my mother was a child, maybe in the 30`s. And I think he visit Marit in Sør-Fron some years ago. I remember my mother talked about Minneapolis, so I guess he is living or have living there, at least in Minnesota. If anyone have info about Olaf, please send me an e-mail. And happy Easter to all of You! Regards, Annelise
