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.
History of St. Louis (1804–65)
The second major group of pre-Civil War immigrants came from Ireland, including both Catholic and Protestant Irish. Although in other regions Irish immigrants were equated with poverty during the 1820s and 1830s, the early Irish community of St. Louis in the 1830s often included wealthy, politically powerful and influential members, such as John Mullanphy, Alexander McNair, and John O'Fallon. However, starting in the mid-1840s large numbers of Irish fled poverty abroad and arrived in St. Louis with little money or skills. Many of these Irish were motivated by the Irish potato famine of 1845–1846 and the failed Irish uprising of 1848.
