"CastleGarden.org is an invaluable resource for educators, scholars, students, family historians, and the interested public. Currently the site hosts 11 million records, and support is needed to complete the complete digitization of the original ship manifests."
Enter a name with as much or as little information (I only used last names) into the search box. Once the results are found, click through the surname for more detailed info such as departure date & point, ship, destination, etc. Really interesting!
