One of my families from Hafslo area are the John Mons Johnson and Anna Ottosdatter Espen family. The other family was the Sjur and Anna Lunde Christenson family. You mentioned a Peter Larsson Ugulen. Peter was born in 1865 to Lars Olsen Kjos and Anna Johannesdtr. Lilleskov in Norway. Peter sailed on the "Augusta" from Bergen in 1853. His brother Ole his wife and son came in 1866 and his parents and three sisters followed on the Bark "Alma" in 1869. His father homesteaded land in section 26 of Nelson township in Buffalo County, Wisconsin. Peter's brother Ole homesteaded the land that my father purchased in Modena township, Buffalo County, WI. I have lost track of the Ugulen family and was glad to hear where Peter ended up. I know he was in the civil war. I have more information on the family if anyone is interested.
