Eitun/Eitorn/Eithun

I'm looking for descendants of Christi Hansdtr (b. 1809) and Botolv Larss. Eitun/Eitorn/Eithun (b.1806). They arrived in New York with the ship Minerva in 1851. They went from Bergen (Balestrand). They had 6 children when they left Norway: Lars (b. 10 Feb 1836), Anne (b. 9 Aug 1838), Hans (b. 13 May 1841), Ole (b. 25 Nov 1843), Erik (b. 5 Oct 1846) and Kari (b.29 Jan 1850). On the same ship was also Christi's two sisters, Kari Fjærestad and Brita Svardal from Vik in Sogn. Kari went with husband and two children, Brita was single. I think both Kari and Brita settled in Kasson, Dodge County, MN. I've found descendants of both. I'm also trying to find out what happened with my g.g.grandfather Alv Olsson Hauglum (b. 1828), from Vik in Sogn. He went to America from Bergen in 1856, unmarried.
