Hey Jeff! Since it has been so long since your initial post, after emailing you, I wondered if you even still had the same email address so I decided to reply here as well. I believe that the John and Elma you seek were my grandparents. John was born in Finland in the early 1890s and passed away at age 95. They had 14 children and 40 grandchildren. Most are in Michigan.
I look forward to comparing notes!
