Hi Jerry,
We are related! My mother was Norma Kjenstad from Brandt, SD. I remember the name Tilman. I think he was a second cousin of hers. Her father was Hans Kjenstad, son of Christian (& Marthea) Kjenstad, whose father was Christopher Kjenstad.
My Mom put together an extensive genealogy before she died 9 years ago, so I will check into that and see if it says exactly how Alfred Kjenstad is related.
Hope you are still checking this board from time to time!
