Irish Canadians
The first waves of Irish immigrants took place between 1763 and 1880. when ten thousand Irish immigrants arrived on the Island. From 1800 to 1850, "10,000 immigrants from every county in Ireland" had settled in Prince Edward Island and represented 25% of the Island population by 1850.
Scotch-Irish Americans
Transatlantic flows were halted by the American Revolution, but resumed after 1783, with total of 100,000 arriving in America between 1783 and 1812. By that point few were young servants and more were mature craftsmen, and they settled in industrial centers, including Pittsburgh, Philadelphia and New York, where many became skilled workers, foremen and entrepreneurs as the Industrial Revolution took off in the U.S. Another half million came to America 1815 to 1845; another 900,000 came in 1851-99. That religion decisively shaped Scotch-Irish culture.
