Went to a funeral this weekend for my daughter-in-law's brother. When I went to update my genealogy information, noticed I had not included much information on her ancestry. Hence, my search and finding your post. I am not sure if John and Anna were my daughter-in-law's great-grandparents, but the dates fit. I did have the information that Anna died in Washington, but nothing more. My daughter-in-law's grandfather was named Lawrence Jensen and her mother was named Betty Jean Jensen, who was born in New Ulm, MN. I really don't know much more about the earlier generations.
Betty Jean had eight children, all in Minnesota.
