Peter Gunderson was born to Aslak and Thoren Gunderson in Norway. He came to Baldwin, Wisconsin, at the age of two. In 1880, they came to Griggs County. He attended the Gunderson School and St. Olaf Church while growing to manhood here.
In May 1889, he married Inga Vrem of Pekin. They lived on the Rognlien farm for a while, then moved to Washington State where they lived for a few years. They returned to the Turtle Mountain area for a short time, then back to Walum. He purchased his father's land on which Walum was located.
In 1905, Peter went into partnership with his brother-in-law, John Broten, in purchasing the Gunderson and Broten store. The Gundersons were active in St. Olaf Church and community affairs. In 1909, they built a new home. The store burned down, so Peter sold his house to Andrew Wogsland for several purebred Percheron horses, and moved to Calgary, Alberta, Canada.
The children of the Gundersons are: Mrs. Alvina Hauge, Mrs. Aria Goudy, Orris of Ols, all in Alberta, Canada; and Irwin who was killed in a mowing accident. Alvina and Aria visited Walum in 1986. Alvina died January 1987. Aria is still in Calgary.
