United States Sheehan migration to the United States +

The 19th century brought a massive reduction in Ireland's population. It seemed that during the Great Potato Famine of the late 1840s the Irish people had two options: starve or immigrate. Those that chose the later frequently headed for the United States, hopeful for land, work, and equality. Those determined for free land joined the migration west; while others stayed behind to live in urban centers and often work in factories. Still others began a transitory life in work camps, building the bridges, canals, railways, and highways so critical to the rapidly development of the growing industrial nation.
