The extended branches of the Finnestad family tree really took off as can be seen by the 1920 US census.
Ole and Mari Finnestad's daughter, Rachel Vallem had 9 children. Rachel's second eldest daughter, Ellen Marie (Mary) and husband Seward Sanderson had 14 children. In 1930 they were living in Milan township, DeKalb County, Illinois with their children Elmer, Walter, Anna, Violet, Marion, Charles, Lillian, Gordon and Ellen.
Living next door was their son Lawrence, his wife Nora and daughter Dorothy.
