Okay this one is a little weird. I remember watching this movie like 100 times as a kid but I forgot the name and can not find it at all

It was a western made probably in 70’s or 80s. More than likely a family film. This teen kid was travelling with his father and a band of Mormons to “the promised land” of Utah. Somehow the father died and the kid wandered off, finds some land and builds a house and a small farm. He find a native girl that he falls in love with. She is hard for him to handle and her tribe try to take her back. But she comes around, teaches him her language and helps him fight off a bear, wolves and natives. Eventually they have a baby and the girls tribe sees he is a good kid and leaves them alone.

Any ideas?
