Section in "A Pioneer History of Becker County", by Alvin H. Wilcox in 1907 reads, "Mr. M. Bjornstad is the owner of a fine farm in the eastern part of Lake Park Township. He is a Norwegian, born in Roken, Norway, September 29th, 1849. In his youth he decided to leave his native country and emigrate to the United States and in June, 1868, he arrived in America. Inspired with the hope of finding a home of his own he proceeded to Minnesota and on the 4th day of July, 1870, arrived in Becker County. He took up a homestead in Section 13 of Lark Park Township, where he still resides. On July 29th, 1873, Mr. Bjornstad was married to Miss Josephine Halvorson, and at the present time Mr. and Mrs. Bjornstad are the proud parents of twelve children, six boys and six girls, George, Joseph, Bendike, Wilhelm, Gabriel, Ferdinand; and Cornelia, Helena, Marie, Nora, Julia and Alma. Mr. Bjornstad has held several township offices such as supervisor, road overseer, and school director. In politics, Mr. Bjornstad has been associated with the republican party. He is also a member of the Norwegian American Lutheran church. By active work and industry he has constructed on his farm large and comfortable buildings in which he and his family now enjoy the comfort and blessings of modern farm life."

The Becker County Historical Society reports that Michael's Naturalization Records show his last name was Janson before coming to America. This must have been a version of Johannesen. Note that those papers list Charles Janson.
There was a Carlo Inglia born to Johan Olsen (not Johannes) and Karen in Royken 6/9/1849. Is there a connection? The Norwegian Emigration Center implies in their letter July 22, 1998, reference #98.701, that this is not the same as Michael, since they did find Michael Johannesen born 10/11/1849 and baptized 11/18/1849 with parents listed as Johannes Olsen and Karen Johanne Olsdatter living on farm Gunnerudeie in the church records from Royken.
