According to O'Rahilly, about two centuries after the Bolgic invasion, Ireland was subjected to another invasion of Brittonic speakers. Three names can be distinguished for them, but whether they were one tribe with three different names or three closely allied but separate tribes we cannot say. These names, as given in later written records, are Laigin, Domnainn and Gálioin. According to their own traditions, they came to Ireland from Armorica (Brittany). They landed in the southeast of the country and took the southeastern quarter from the Érainn. The modern name of this province, Leinster (Irish: Laighin), preserves the memory of this Laginian conquest, although in ancient times it was much smaller than the modern province. Before the Goidelic invasion, the River Liffey marked the boundary between Ulster and Leinster. The Domnainn were clearly a branch of the Dumnonii, a Celtic people identified by Classical authors as inhabiting Dumnonia (the English counties of Cornwall and Devon, to which they gave their name). Another branch of the Dumnonii settled in Scotland, where they founded Dumbarton and established the kingdom later known as Strathclyde. Presumably these settlements occurred at around the same time as the Laginian invasion of Ireland. It is even possible that the Dumnonii of Scotland were originally Irish Domnainn.
