Born 1868
From An illustrated history of Jackson County, Minnesota (1910)
PETER O. ANDERSON (1868) is one of Jackson county's native sons, having been born on his father's old homestead in Belmont township September 13, 1868. He is the son of the later Ole A. Aas and Caroline (Lilleberg) Aas, who came from Norway when young and who were married in Jackson county soon after their arrival in 1866. His father died in Jackson in 1906; his mother lives in Jackson.
Our subject took the name Anderson in preference to that of Aas when a young man on account of the similarity of names in the neighborhood. Until his marriage in 1896 Mr. Anderson lived with his parents on the old homestead on section 4. He then bought his present farm on section 9, where he has since resided. He is a member of the Norwegian Lutheran church.
Mr. Anderson was married in Jackson county April 12, 1896, to Annie Hanson, a native of Belmont township and a daughter of Jonas Hanson that pioneer settler of the township. Six children have been born to Mr. and Mrs. Anderson, as follows: Clara, Joseph, Obert, Maurice, Pearl, Henry.
