The year 1842 records the beginning of the great development, which in five years resulted in the settling of almost the whole of this vast area by immigrants from Norway. The next year was that of the great influx from various points in Telemarken, especially, Siljord, Laurdal and Hvideseid, although there were considerable numbers also from Vinje and Tin. The year 1843 was the one in which the Telemarkings took possession of Koshkonong; they gradually selected their permanent homes in Pleasant Spring, extending into Dunkirk and Cottage Grove and the northeastern sections of Christiana (as Eggleson, Bjoin, Hauge, Borgerud, Bosbön and Kingland). The Numedalians came only in limited numbers after 1842 and did not spread much beyond the original center around East Koshkonong church in southeastern Christiana and northern Albion townships. Those on the extreme west were Levi Kittilson, Levi Holtan, O. O. Lenaas and Tore E. Smithback, all coming somewhat later than those in the eastern extremity. The immigration from Numedal, which began in Rollaug, is after 1842 almost confined to Flesberg, a parish which furnished no immigrants before 1842. In the year 1843, there came to Koshkonong, 35 families and many single persons, or a total of 182 individuals. This was the year of heaviest immigration to Koshkonong. The year's influx is significant in the large number of districts in Norway represented, Telemarken leading as has been pointed out above. In addition to 9 persons from Numedal, and a small contingent from Voss, the first party of fourteen persons arrived from Kragerö. These first immigrants from Kragerö were: Bjorn O. Rom, Kjöstolf Tollefsen Hulderöen[265] (b. 1821), Even E. Buaas (b. 1799), Abraham K. Rönningen, Erick K. Rönningen, Halvor E. Dahl (b. 1802), wife Anne, and family, Torbjörn K. Rönningen, Glus P. Tyvang and wife, Audi, and Peder K. Rönningen. From Leikanger in Sogn[266] Anna L. Eggum (or Eggene, b. 1811), who in 1845 married Sjur C. Droksvold, from Voss; from Lier came Knut O. Lier, as also the widow Anne Thorstad, Knut Asdöhldalen and Gabriel Björnson (from Drammen); from Drangedal came Baruld J. Strandskougen and family, from Sandsværd, Ellef A. Berg, from Skauger, Halvor J. Stubberud, from Rögen, Lars P. Haukelien and family, from Holte, Tarald E. Midböe, from Gjerpen, Peder H. Moe, and from Hallingdal, Even Olson. [265] Came to Muskego in 1843, went back to Norway and returned, settling in Koshkonong in 1846. [266] There was one immigrant from Aurland, Sogn, in 1843, but he stopped the first winter in Muskego.
