Amund was born January 24 1806 in Hadeland, Gran in Norway Pernille was born February 4 1810 in Hadeland, Gran in Norway. In May 1 1851 they left Gran and there destination was America. It says that they went with bark Richard Cobden and Mads E. Langgaard was captain on this boat. They left from Christiania[Oslo] May 22 1851 and came to New York August 2 1851. I want information about where they went and if they had children. Are there anyone who want to help me with these two?
