The first week of January 1892 saw the opening of a new U.S. immigration station on Ellis Island in New York Harbor. A 15-year-old lass from Ireland named Annie Moore entered the United States and history when she passed through its doors, becoming the first immigrant to be processed there. Over the next 62 years, 12 million more would follow, making Ellis Island the most famous entry point in America.
Ferryboats full of eager immigrants who had just crossed the Atlantic on sailing vessels or steamships docked at Ellis Island. There passengers disembarked to be screened by doctors and immigration officers. If they were in good health and their papers in order, they were allowed into the United States. Over the years, 98 percent of all those examined at Ellis Island were admitted into the country. More than 40 percent of all U.S. citizens can trace their ancestry through those immigrants.
