Here is the 1910 US Federal Census I have for the remaining child of Ole and Mari, Rachel (Rakkel) Vallem.
Rachel was widowed by 1910 and living in Alto Township, Lee County, Illinois with her son, Ole and Elmer & daughters Linnie Rebecca, and Iverdena (listed as D Anna).
Rachel's brother, Ole Finnestad Jr and family were living in the same township.
Living next door was Rachel's eldest son Peter, his wife Lena and their children, Lawrence, Perry, Lucille and Lena.
As I stated in an earlier post, I was unable to locate Ole and Mari's daughter, Mary and her 1910 census record. If I come across it, I'll post it.
