I was looking for a place to find out about where my grandfather had his homestead farm near Coronation/Lake Thelma Alberta Canada. Googling Lake Thelma, your post came up. I notice that you have a Kolle surname. There were a number of Kolle's around our ancestral home near Wendell. MN
(near Fergus Falls, MN). My mother's birth certificate states Lake Thelma. Her father was Harry Wangsness (her mother died in child-birth). Maybe I could find her gravestone at Coronation. Grandpa Harry farmed there until the early 50's. Thanks for the post. Roger Lillemoen
