The Ellis Island database lists 4 Olaf Andersen/Andersons immigrating from Norway--2 in 1910 and 2 in 1912. There are several possibilities for Alfred Hansen. I did not find a Lillian Hansen immigrating in 1913. If you wish, you may take a look at
www.ellisisland.org. There is no fee for searching the database.
