Information on Albert Nielsen born 1839/Sverige

From what I have found is Albert Nielsen was married to Karen Marie Larsen born 1848/Kristiania. They had 4 children Borger born1879,Sofus Pauli born 1880, Karen Albertine Nielsen born1884 and Viktor Nielsen 1891. I did find Viktor came over to New York 1904 with his mother on the Teutonic in 1904. If anyone has anyother information on this family I would really appreciate it. Albert was born1839 in Sverige.
