In the extreme northern part of Dane County in the Towns of Vienna, Windsor and Bristol, a large number of Norwegian immigrants, principally from Sogn, settled in 1846-1848, forming the nucleus of what in a few years came to be one of the most prosperous settlements in Southern Wisconsin. The first Norwegian in this section was Svennung Nikkulson Dahle, who came from Flatdal in Telemarken in 1844 to Koshkonong, and the next year purchased land and settled near Norway Grove in the Town of Vienna. He was then only eighteen years old.[360] Nearly all who came later were from Sogn, and Dahle was and remained the only native of Telemarken in Vienna. In 1846 Erik Engesæter, from Leikanger, Sogn, with family, including a son John, settled there. In 1847 Ole H. Farness (b. 1826) and wife Gertrude came from Sogn, Norway, to Norway Grove. Erik C. Farness[361] (b. 1828) also came the same year. These men both acquired large farms there in the course of time, Ole Farness owning 530 acres. Arne Boyum and family, five in all, from Outer Sogn, came in 1848 as did Knut K. Naas (b. 1810), with wife Alau and family of four children from Kragerö.[362] [360] About 1858 he married Maline Öien (b. in Aardal, Sogn, in 1835). Svennung Dahle died in 1872, the owner of 400 acres of land. [361] He was married to Ingeborg Grinde in 1851, Rev. A. C. Preus performing the ceremony. Ingeborg was the daughter of Botolf Grinde who came from Sogn in 1846 and settled on Liberty Prairie. [362] Two sons, Thomas and Isak, went to the War in 1860. Thomas was killed in the Battle of Antietam, September 17, 1862. Knut Naas died in 1868; his wife in 1887.
