Another class confirmation class with Ole and Mari Finnestad's descendants was in 1911. When I originally posted two years ago, I didn't know of the Sanderson family link.
Ole and Mari's granddaughter, Carrie Evelyn Finnestad is seated in the middle row, 3rd from the left. Carrie's parent's were Caroline (Quitno) and Ole Finnestad Jr.
Ole and Mari's great grandson, Lawrence Alvin Sanderson is seated next to Carrie on the left. Lawrence's parents were Ellen Marie/Mary (Vallem) and Seward Sanderson, his grandparents were Rachel (Finnestad) and Lewis Vallem.
