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.
Irish Americans
Down to the end of the 19th century a large number of Irish immigrants arrived speaking Irish as their first language. This continued to be the case with immigrants from certain counties even in the 20th century. The Irish language was first mentioned as being spoken in North America in the 17th century. Large numbers of Irish emigrated to America throughout the 18th century, bringing the language with them, and it was particularly strong in Pennsylvania. It was also widely spoken in such places as New York City, where it proved a useful recruiting tool for Loyalists during the American Revolution.
