Information on Johannes Berge

I would like some more help from the members. Specifically, in tracking down information on Johannes Berge. Since December 2007, the forum members have been helping me find information on a Halvor Johannessen (Johnson). We ran into a dead end in trying to find out who Halvor's father was. Today I ran across a Post on a genealogy board which leads me to believe his father could be a Johannes Berge from Hegebostad in Vest Agder. Here is the Post from the board. I’m looking for one of the earlier emigrants from the Stavanger-region, Rogaland, Norway. In 1850 Halvor Jonsen, also known as Halvor Johannesen and Halvor Berge, emigrated from Jåsund, in the Sola municipality, to North-America with his family. He left his farm together with his wife Ingeborg Tjerandsdatter Helland, their 8 children plus their son Johans wife Karen Malene Hansdatter from Revheim in Madla. Halvor was born around 1803 a son to Johannes Berge from Hegebostad in Vest Agder, and in 1826 he married Ingeborg. Their first child, Johan, was born in 1827. The later children are: Marta Oline, Ingeborg Helene, Karine, Gunnhild, Anna Kristine, Halvor and Carl Johan. Johan married Karen Helene April 4th, only 5 days before they are noted in the church book as left for America. A friend of mine is trying to find any descendants og trace of this family in America. Please put your resources to work and help her. Any hints will be of great help. Atle This information is a direct match with information I have on Halvor's family. Would you all help me out and see if you can find information on this Johannes Berge. Thanks a lot. Richard
