Celtic Ireland in the Iron Age: the Celts
The Celts of Ancient Ireland

"By the mid-1st millennium, with the expansion of the Roman Empire and the Migration Period of Germanic peoples, Celtic culture and Insular Celtic languages had become restricted to Ireland, the western and northern parts of Great Britain (Wales, Scotland, and Cornwall), the Isle of Man, and Brittany."
"Insular Celtic culture diversified into that of the Gaels (Irish, Scottish and Manx)"
"The Celtic languages form a branch of the larger Indo-European family. By the time speakers of Celtic languages entered history around 400 BC, they were already split into several language groups, and spread over much of Western continental Europe, the Iberian Peninsula, Ireland and Britain."
