The next confirmation class with multiple Finnestad descendants was 1913. I'd posted Ole and Mari Finnestad's granddaughter, Lillian's photo and ledger in 2009.
Ole and Mari's great grandson, Elmer Seward Sanderson was in the same class as Lillian Finnestad.
Lillian Finnestad is seated in the bottom row, far right.
Lawrence is standing in the back row, second from the left side of the photo.
Lawrence's parents were Ellen Marie/Mary (Vallem) and Seward Sanderson, his grandparents were Rachel (Finnestad) and Lewis Vallem.
