I seek information on Charles (also known as Karl) Ludwig Danielson (1855-1922) and his wife Maria Mathilda Jacobson (1854-1893) who came from Sweden to Polk County, Wisconsin in 1881. I know that Maria's parents (John Peter Jacobson and Eva Andersdotter) also moved from Sweden to Polk County (along with Maria's brother Victor and sister Selma) in 1891. But I can find no record of parents or other relatives of Charles Ludwig Danielson in either Sweden or the United States. I am curious as to why Charles and Maria emigrated to Wisconsin. Any information about members of this family would be appreciated.
