Just the way it is.
Current theory (demonstrable at the level of mtDNA) is that Europe was repopulated after the Ice Age by local populations that'd been located in what is roughly the Basque regions South of the Pyrenees.
That's ALL OF EUROPE, not just a little teeny tiny bit.
The older theory had Indo Europeans riding in conquering all before them, becoming dominant, and eliminating whatever bit of the natives they'd met.
One does suppose they ate them eh.
The current theory explains the flow of Indo European languages to the West and North with the movement of agricultural populations from the Middle East!
They moved in. The natives stayed. Some of the natives adopted herding. Some adopted farming. Some moved on up the mountains. Whatever. And they adopted the newcomer's languages simply because they had more and better words that reflected their higher level of technology ~ to wit, growing food!
This leaves us with a simple solution to the problem of how the Irish (Ir is the eldest of three brothers in the ancient myth) came to live in Scota (the land of the Great Goddess). Scotland was initially known as Alba but that was changed in the very recent conquest in the 9th century (simultaneously with the Norse).
It may be a Koinkydink that the ancient Galician records conform to the DNA trail, and that the English stories don't, but I think that's unlikely.
Even Sassanach histories reflect the renaming of Ireland to Scota, and Alba to Scotland ~ your own stuff ~
Now, back to where Galicia was located, it's the entire NW corner of Iberia. Their own gaelic language died out in the 1300/1400 period as best anyone can tell and was replaced with a form of Spanish and/or Portuguese. There was a period of rapid change at the time of the transformation. A couple of other major Gaelic languages were eliminated during the same period in France and were replaced with Gallo (which is like French), and then by French based on the standards of the Isle de France. Breton (a Welsh dialect) is still spoken widely in Brittany. Even both forms of Welsh are spoken in Wales. Cornish died out in relatively modern times but there are still people who are keeping it alive. And so on.
Whatever you think of the alleged Sassanach sources for the various names of the peoples and countrysides of the Celtic Fringe, "Wal" and "Gal" and "Gaul" and "Xal" and wide variety of other variations on that theme have been in use the days the Phoenicians living in their colony of Carthage called their ally in Europe by a name rhyming with the Greek version of the same which was "Magolis", that is, McWallace, and that's pretty doggone ancient ~ but as much as you think the word for that type of folk originated with the Greeks and Romans, the Carthaginians had an even more ancient history of literacy and civilization and they, too, referred to the tribes and leaders according to the very same nomenclature the Galician records use.
Someday you Brits will figure out that the Naaaatives have their own names for themselves ~ then we won't keep running into this "change "the ukraine" to Ukraine" or "Bombay is now Mumbai" business. It's more difficult to change than to get it right the first time.
Oh, yeah, and the 1000BC to 700BC stuff, that's the same time frame the Galicians from the Danube who didn't take the Mediterranean to Spain went to Anatolia and settled in the midst of all the better known ancient peoples.
Everybody knew they were there ~ by Roman times they were known as the Galatians.
But, here's the kicker for you, whatever name the Greeks used for them, that place referred to as "The Gleaming Towers of Illium" ~ others described it as "The Gleaming Towers of Allium" ~ and there's yet another form of "Gal" ~ with the soft A rather than the more guttural sound the primitive Sassanach could only describe as "X" in their Runic alphabet.
What part of Ulster/Scot/Welsh/Danish did you *not* understand?
You must be a moron.
"Ir is the eldest of three brothers in the ancient myth)"
I care nothing for your fairy tales and "myths".
I am interested only in proven scientific archaeology/anthropolgy.
"Even Sassanach histories reflect the renaming of Ireland to Scota, and Alba to Scotland ~ your own stuff ~"
Do NOT -ever- call me a Sassenach [the -correct- spelling; note that] again, you little fairy-tale spewing, Google-hunting lackwit.
And you screwed up the famous 'historical identity' of the Galatians.
[I'm *so* shocked] /s
They were the Gallic people who were living in modern day Turkey...those very same people that St Paul had such a "problem" with.
[does the Biblical chapter of "Galatians" ring a bell?]
"McWallace"
Love to break this to you but -Wallace- is a name of WELSH origin.
There are Wallaces in Scotland *now* but they originated in Wales.
"This leaves us with a simple solution to the problem of how the Irish (Ir is the eldest of three brothers in the ancient myth) came to live in Scota (the land of the Great Goddess)."
No.
This leaves us with the same insane fairy tale delusion you embrace as "history".
Again, there was NO "Queen Scota" and no son "Ir". There is ONLY "Eire"
"EtymologyFurther information: Ériu, Erin, Hibernia, and Iverni
The modern Irish Éire evolved from the Old Irish word Ériu, which was the name of a Gaelic goddess.
Ériu is generally believed to have been the matron goddess of Ireland, a goddess of sovereignty, or simply a goddess of the land.
The origin of Ériu has been traced to the Proto-Celtic reconstruction *Φīwerjon (nominative singular Φīwerjō).
This suggests a descent from the Proto-Indo-European reconstruction *piHwerjon, likely related to the adjectival stem *piHwer- (cf. Sanskrit pīvan, pīvarī and pīvara meaning "fat, full, abounding"). This would suggest a meaning of "abundant land".
This Proto-Celtic form became Īweriū or Īveriū in Proto-Goidelic.
It is highly likely that explorers borrowed and modified this term. During his exploration of northwest Europe (circa 320 BCE), Pytheas of Massilia called the island Ierne (written Ἰέρνη).
In his book Geographia (circa 150 CE), Claudius Ptolemaeus called the island Iouernia (written Ἰουερνία).
Based on these historical accounts, the Roman Empire called the island Hibernia. Thus, the evolution of the word would follow as such:
Proto-Celtic *Φīwerjon (nominative singular Φīwerjō)
Proto-Goidelic *Īweriū or *Īveriū
Old Irish Ériu
Modern Irish Éire
Another etymology is from the Gaelic:
ì (island) + thairr (west) + fónn (land), which together give ì-iar-fhónn, or "westland isle"[3]
This is similar in meaning to the Norse name for Irish people, "west men", which subsequently gave its name to the Icelandic island of Vestmannaeyjar"
In closing;
"Do an leathcheann."
Google that.
Now, I have about 30Gs of software to install and no more time to spare on your "Pop-Up Book of the History of Ireland".
Bugger off, poseur.
By the way, my surname derives from the greatest and most ancient of all [proto]Celtic deities, Lug.
Variations and derivatives of his name can found ALL over Europe, from the Rus steppes, all of the UK, Spain, France, Italy, even unto modern London which was, in the begining called Lugdunum, or “fortress of Lug”.
My fraternal grandmother’s name derives from Surtr, the Norse warrior of Ragnarok.
[and on my mother’s side, her mother’s name derives from “Thor” and her father was of clan MacBeth so Google that]
“Sassenach”, my royal ass.
