I did check the spelling, but can't find Mrs. Schearl mentioned any where in this article. But, I did some research and this novel tells the story of David Schearl, an immigrant boy who comes to the United States in the early 1900s and grows up in the dark, crowded tenements of New York.
Maybe this should be the question instead; What happens when David and his mother first arrive at Ellis Island?
Hope this information helps. So I assume we need to find out what happens when David and his mother first arrives at Ellis Island, then we can write a brief description of her trip to America.
