"WHERE DID THE IRISH COME FROM ORIGINALLY "
This may be of interest to someone searching for their irish descendents and where they may have come from .
This answer was from the following source = YAHOO! ANSWERS -UK AND IRELAND in answer to the questions below
Where did the irish come from originally?
where they always there or were they danes originally?
Actually all of these answers are wrong so far.
The first Irish crossed from Europe after the last Ice Age; they came from the Basque region of Spain,and this strand of DNA is still the most prevalent in Ireland today (over 90% of Irish people have it, in both Y chromosome and mit dna). They were hunter gatherers primarily.
Later, smaller groups of people came down the western seaboard and settled,bringing agriculture, which soon was adopted by the native populace. this was the time of building great monuments such as Newgrange,which, like Stonehenge in England, was sacred to the ancestors and aligned on the midwinter solstice, although in Newgrange it was solstice sunrise rather than Stonehenge's sunset.)
The celts arrived in around 400 BC but there is no evidence that there was any mass immigration from the so-called celtic heartland on the continent,as is proved by the recent dna findings. It would be logical to suppose that the pre-celtic people, who have no name as they did not use writing, also spoke an early form of celtic so could be regarded as proto-celts.
The vikings came to Ireland as well, and left some small genetic stamp mainly around areas of heavy settlement such as Dublin. In the remote west, where gaelic is used most, you get the highest rate of aboriginal dna,and also 'the black Irish' whose darker hair and complexion probably came from their Basque-type ancestors.
