Data has been extracted from records at the Ellis Island web site. At minimum, data was copied from the Passenger Record. In many cases, data was also copied from the text version of the manifest, and, if possible, from the original (image) version of the manifest.
If "Manifest Image" is Yes, the manifest image is available and it has been downloaded.
If "Edit Complete" is Yes, the data from the manifest has been entered in the database.
