CatleGarden.Org offers free access to an extraordinary database of information on 10 million immigrants from 1830 through 1892, the year Ellis Island opened. More than 73 million of American can trace their ancestors to this early immigration period. Castle Garden is the major landmark within The Battery, the 23 acre waterfront park at the tip of Manhattan. It was the first America’s official immigration center. It represents a very valuable resource for educators, scholars, students, family historians, and the interested public. Currently the site has 10 million records. At the left hand side of the homepage there is a quick search box to search for individuals or families; you can do that by entering passenger’s first name and last name, and the range of dates for their arrival. At this website, you can do more advanced searches and learn more about the Battery Conservancy, an antique no-profit educational corporation to rebuild and revitalize the Battery and Castle Clinton National Monument.
