The information I have is that Leonard Jensen's wife's name was Florence, and I received this information from my Dad who was Leonard's brother and also from Leonard's granddaughter Melody. However, the Jensen's in my family had very strong ties to Minnesota. My father and all his siblings were born and raised in Minnesota. Only a few of the family moved to Washington. Most stayed in Minnesota.
What is your daughter-in-law's maiden name? Also, I would like to know if she knows any other relatives names. As it stands now, it does not seem as thought the connection works.
I am looking forward to hearing back from you.
