Looking for data on Lars (Olson) Sigedahl from Rangtvedt, Norway. Father's name was Ole Olson, (a fisherman), and his mother was Astri (surname unknown). Lars was a carpenter and married Thorbjar Thorson in 1849 at Stavanger, Norway. She was from Heggeflatta, Suldal and the daughter of Thore Thorson and Breta (surname unknown). They lived in Sigedahl near Stavanger from 1849 until they immigrated in 1866. This is where the surname Sigedahl probably came to be. They lived in Lac Qui Parle, Minnesota for several years and then moved to Dover Township in Northeastern Iowa.
I am also looking for data on Askel Askelson Underbakke (b. December 21, 1849; d. October 1, 1921). He was from Sand, Norway and immigrated to Dover Township in Northeastern Iowa in 1872. His father was Askild Torson Underbakke (b.1813) (he took the surname Underbakke in 1836) and his mother was Haldis Oldsdatter (b. 1815; d. 1885) from Rogntveit, Mehus.
