In 1921, Ronan and Patrick Dooley leave their family in Ireland to start a new life and a better future in New York City in America.
Between 1892 and 1924, 12 million immigrants arrived in New York. They were usually poor, but believed in "The American Dream" - if you work hard, you can get a good job, a nice home and money.
Today, New York is still a place of hope for new immigrants - just like Ronan and Patrick.
