Bertha Josephsen was born on 6 December 1862 in Frederikssund, Sjælland, Denmark, to Niels Josephsen and Maren (Willums-datter) Josephsen. Bertha Josephsen was the third of seven children. The family owned a hotel and later moved to a farm near Fredericksvard. The children were educated in public schools and also helped out on the farm along with hired men. Bertha was sent to a large dairy farm on the island of Fyn when she was eighteen. Here she met her future husband, Peter Anderson, and they were engaged for nearly two years before marrying on 17 August 1883. After Bertha and Peter were married, they moved to a farm near Bertha’s home. Their first child, Mary, was born in 1884, and following that they had a son, Niels, in 1885, and another daughter, Dagmar, in 1888. After three of Bertha’s brothers moved to America, the family decided to emigrate as well, traveling across the Atlantic to New York in a large ship, and going by train and stagecoach to Sidney, Montana, where they homesteaded. The family faced many complications while settling in during the first few years, including food shortages during the winter, paying off debts, battling prairie fires, unexpected encounters with Native Americans, and a lack of close neighbors or facilities to go to for help. After 1898, Bertha’s mother and thirteen other relatives joined them in Montana. Bertha and Peter had eight children in all. Bertha was active in helping new settlers in the area and she and her family played a great role in establishing a Danish Lutheran Church in the area, and were founding members of the town of Sidney, Montana. Bertha Anderson died in April of 1955 in Salt Lake City and was buried next to her husband in the cemetery in Sidney.
