Answer:
After leaving Ellis Island, the newcomers went on to live in many different places.
Step-by-step explanation:
Russell Freedman in his book "Immigrant Kids" tells of how young newcomers to America had to undergo various trials and hardships to get to their destinations. It gives a rare insight into the lives of these immigrant kids and their ordeals during their journeys.
For these kids in search of freedom, they had come to America, the 'land of the free'. But the freedom they encountered was of a different kind. They had to do menial and odd jobs if they are to survive in the new place.
Ellis Island is the immigration station that enables the U.S. government to check the influx of immigrants into it's soil. The passage in the question is a perfect paraphrasing of the newcomers who left Ellis Island to live in many different places.
