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.
Gaels
Christianity reached Ireland during the 5th century, most famously through a Romano-British slave Patrick, but also through Gaels such as Declán, Finnian and the Twelve Apostles of Ireland. The abbot and the monk eventually took over certain cultural roles of the "aos dána" (not least the roles of "druí" and "seanchaí") as the oral culture of the Gaels was transmitted to script by the arrival of literacy. Thus Christianity in Ireland during this early time retained elements of Gaelic culture.
