Thanks for the response.I'm not sure there is a connection here though.The Paulsens I'm trying to track were the children of Johann Paulsen (1794-1867) and Johanna Catharina Margaretha Hayken (1792-1835).Two of their children, Hans (b. 11 Nov 1823 d. June 1890) and Elisabeth (b. 29 Oct 1825), immigrated to Iowa.I'm not sure of the timing, but assume it must have been sometime around mid-century.
Hans married a woman who was, I believe, born in Iowa named Christine Kroger.I have some evidence that they had children, but I have no other information on them.
Perhaps something here will match up to your family, but even if not, thanks for the reply.
