This is definitely the son of Stener and Olena (Nilsdatter) Oleson of Mt. Morris in Waushara County. He and wife Sarah A. also appear in Packwaukee in 1930, but daughter May is not present. May was born in Illinois in 1898 and adopted as a very young baby. Sarah's maiden name was Harrington, and her family was from Maine before they show in the 1880 Waushara County census.
