Lars was the son of Hans Pedersen Aamodt (1820-1895) and Karen Larsdatter Possum (1820-1891).

Lars was born on the Aamoth Gaard in lands Turpen, Prestegjeld, about 40 miles from Lillehammer, Norway on May 10, 1850. At the age of eight, he moved with his parents to Faaberg, where his father had puchased a farm "Lien Nordre", one Mil from Lillehammer. Note a Norwegian Mil is 10 meters or 6 miles). In the spring of 1868 he traveled with his sister Agnethe, who was married to Johannes Pederson Lien, to America. They went with a sailing vessel, and the trip lasted 10 weeks before they arrived in America. They came to Rock Prairie, Wisconsin, in August of that year and stayed there with relatives, who had been there for several years. Lars stayed there until the fall of 1871, then he went to Zumbrota, Goodhue Co., Minnesota, where his sister and brother had gone earlier. Members of his family, with the exception of Lars, left for Goodhue County, Minnesota. In the beginning of April 1872 he went by the railroad westwards to find a home of his own. He first made a stop at Oak Lake, Becker Co., Minnesota, where his brother Peter the year before took land. After a while he went with his brother Peter, who had sold his Improvement by this time, and Andrew Hanson and Jens Urdahl, to Wild Rice River, Norman Co., (at that time Polk County). The three first mentioned took each one 1/4 Section land in Fossum Township, and Jens Urdahl took land in Flom Township. On this land, which he took in 1872, Lars set up shop. Lars later changed his name from Aamodt to Aamoth. Lars remained in Wisconsin to work and learn more of the English language.

While there he met Ingeborg Rostad, whom he married on September 24, 1872 in the Zumbrota Church by Pastor Nils Ulvisaker. The couple joined the Aamoth families in Minnesota in what is now Fossum Township. Lars was a farmer and later was in the hardware business. The couple had 10 children together, of which 8 lived to old life. The family moved to Portland, Oregon, where Lars continued in the hardware business. Lars died December 9, 1931 in Portland, Oregon.
