Pearl B. (Tharaldson) Johnson was born August 29, 1896, on a farm near Pekin, North Dakota, in Nelson County. She lived there until 1907, when she was sent to live with an aunt in Grand Forks. While there she met and married Louis Johnson, a farmer born in Telemarken, Norway. Pearl was fourteen at the time of their marriage. Louis and Pearl began their married life two miles north of Pearl's parents at the Oscar Smith farm in Nelson County. After Pearl's father died, they rented her mother's farm for a few years. In about 1916, Pearl and Louis lived on a homestead in McKenzie County. Five years later, when iron polluted their farm's water supply, they returned to the Pekin farm. In 1947, Louis and Pearl moved to Minneapolis, where Louis managed the Gronna Memorial Home and Pearl served as the home's matron.
Louis and Pearl had ten children, four boys and six girls. Louis died on January 14, 1963. Pearl died on September 20, 1979, at the Community Hospital in McVille, North Dakota.
