I found Mathias' obituary that says he died in Nye, Polk County Wisconsin on January 24 1928.
His daughters are Mrs. Frank Hjelle of Nye and Mrs. Samuel Foss of St. Paul, MN. Also says his wife's maiden name was Penninggrud. He is buried in the West Immanuel Church Cemetery.
Additionally I found a blurb about a Lars Larson who died in Alden on June 25, 1877 aged 65 years.
Hope this helps.
