I found them in the 1920 census at the ages you list, in the town of Mason.
In 1910 they are in the town of Shell Lake in Washburn County.
In 1930, they are still in the town of Mason. There are two more children, Paul, age 9, and Gerladine, age 7. There is also a granddaughter, Jacqulyn Edmunds, age 1. The census says Rose is married, so perhaps that is her child.
