Search Ellis Island Database in ONE step – This site allows you to enter all sorts of information in one easy step and then be taken to a list of matches on the Ellis Island site. You can search just by one letter of the surname and the name of the ship if that is all the information you know. Lots of EASY search capabilities on this site.

CastleGarden.org – This website allows you to search arrival records to Castle Garden, which was open before Ellis Island. You can search from 1820-1913. As far as I could tell, you can not see the actual ship manifest images as with Ellis Island, but it does say that a ‘comparative data’ section is under construction.
Ancestry & FamilySearch – Both of these websites have a great collection of ship manifests including all New York passenger records. However, Ancestry has manifests for more ports, including New Orleans, Boston, Baltimore, Philadelphia and others. If you don’t find your ancestor coming through Ellis Island or CastleGarden, make sure you check other ports through Ancestry.
