I apologize again. I now see where I am mixed up. After doing a bit more research, I see that Betty Jean is your daughter-in-laws MOTHER, not her grandmother. And yes, this John P. Jensen and Anna N. Knudson are the folks you are looking for. If you have access to Ancestry.com, you can see the entire tree. If not, I will send you whatever information you wish.
John and Anna Jensen are my grandparents. My dad is John and Anna's youngest son.
