Halvor J. Halvorson was born in Gjerpen, Telemark, Norway on March 8, 1846 to Ole Halvorsen and Johanne Marie Johannesdtr. They immigrated to the U.S. in 1855. In 1860, he was living in Oconomowoc, WI with his parents and siblings, Ingeborg (1838), Anna (1844), John (1850), Clemmen (1854), and Niels (1860).

Halvorson joined the WI 15th Infantry, Company D. The men of the company called themselves the “Norway Wolf Hunters.” They were also known as the “Waupun Company” because so many of its members were from Waupun.

The army listed Halvorson as living in Oconomowoc, Waukesha County, WI, age 15, and unmarried. He enlisted for three years on October 30, 1861 at Oconomowoc, and mustered at Madison, WI on December 10, 1861 as a Private (Menig). He was assigned as Musician. He was sick in Nashville, TN on December 1, 1862. He became unfit for service and was discharged from the service for disability on February 7, 1863 at Nashville.

In 1870, Halvorson, his parents, and siblings were living in Linden, Brown County, MN. He was helping on the family farm. On October 8, 1876, Halvorson married Caroline T. Oleson in New Ulm, Brown, MN. Their children were: Oscar Theodore (1877), Betsey Josephine (1880), Lorens (1883), Emma L. (1885), Ella M. (1887), H. Clarance (1889), and Albert (1891). Halvor and Caroline continued to live in Linden, MN.
