Most immigrants coming to America arrived from Ireland and Germany.

Many Irish went to the emerging textile mill towns of the Northeast, while others became longshoremen in the growing Atlantic and Gulf port cities. Half the Germans headed to farms, especially in the Midwest (with some to Texas), while the other half became craftsmen in urban areas.
