I didn't realize it when I originally posted it, but the daughter of Rachel and Lewis Vallem, Ella Bertina Vallem was in the same confirmation class (at Calvary Lutheran Church in Lee County Illinois) as Dina Josephine Finnestad.
The spelling is incorrect in the photo "Wallem", but the ledger seems to be Vallem, and also lists Rachel underneath "Mr and Mrs Ole Finnestad" the parents of Dina.
Here is the photo again:
"Dina" Josephine Finnestad is wearing a ribbon in her hair, middle row, 3rd from the right.
Ella Vallem is in the first row on the right hand side.
