Thank you very much. You have opened my eyes, and i am not being sarcastic. Dub does mean deep but in case of Dublin, i think you are right. it probably was the oak place, place with many dubs oaks. Oak, apart from being the sacred tree of both "Celts" and Slavs, (but not the Gaels, they had Holly) was also the main building material for Wendish ships, as opposed to Norse ships which which were mostly built of pine. From that point of view Ireland was a very important as it was in the early medieval time covered in old oak forests. Dublin is in old Irish pronounced dubljin. dubljin in Serbian is an adjective meaning full of oaks. Maybe this is why Gaels called first "Vikings" dubh gall. Irish historians have no explanation for this name by the way.
In Serbia there are many place names built in the same way: Vrčin, Beljin, Kovin, Vidin...
Current Irish interpretation is just transliteration.
the oak tree religion is not characteristic only of the one you mention,
search the word Δρυοπες driopes which was a minor Asian tribe that came to Greece and from there went North and West,
the most famous oracle of Graioi (Greels) is named Δωδωνη dodona and oak tree was worshiped there.
the terminology Celt is after Greek authors who named a tribe in Panνoni basin as κελτος keltos
today we consider Haalstat/La Tene as land of known celtic culture and we can guess the time of proto-Celts first spoken, but how certain we are about the place that proto-Celtic were developed?
the existance of Scordiskii in Balkans in areas among Greece today Albania and Fyrom and their devastation to Serbia around Beograd, as also the existance of Serdi, much before the entrance of Galatians, at least for me means either that Celtic imported Balkans before Historical times, either that Celtic is the Driopes culture of minor Asia.
Personally I believe in Anatolian minor Asian Hypothesis, and I believe that proto-Celts were minor-Asians who moved at agricultural revolution of Europe to Central Europe and there they meet Northern Europeans Hunters and create the known culture, I believe that Celtic is culture that created when farmers meet Hunters and is the older culture that kept id until Roman times, while others created Nations in that time,
The Slavic language is considered the Language of Great Moravia which is next to the area that Greeks put Keltos, north of the Pannoni Basin and connected with it via Morava river.
so the main question is how much Celtic spoken there at the time of Cyrill wrote down and teach Slavic language,
Personally I consider Slavic as a major Σκωλοτοι scoloti-sculoti language relative, although the existance of some scattered (scatter = scord-iski) Celtic tribes in Balkans puts a question,
but if the Driopes can be considered as Celtic or proto-Celtic that means that were farmers, and coal producers who came from minor Asia,
remember driopes means oak+hole, it means the ones who can see the future though a hole in oak wood, exactly the same that Druids do.
the known areas that tribes of Driopes and Celts in Balkans are
Driopes
Lands of Myrmidones and Graioi
means Phthia and Epirus
Celts as Scordisci known moves and culture, unknown origin,
area among Albania and Fyrom and Kossyfo
there is a theory that Illyrians were IE Celts + non IE Pelasgians
Belingrad
Sophia
Celts as Galatians known historically their origin
Scanza mountains bulgaria
West Romania
so the possibility that there is Celtic DNA in Serbia is open and possible, as also some linguistic remnants in areas,
also the connection of Celtic with Slavic of Great Moravia since both IE and according authors both starting points (Pannoni Basin , Great Moravia)
But that does not mean Celts=Slavs or opposite
simply if we consider Kurgan Hypothesis that means that Celts entered Europe much before Germans or Slavs so they left remnant words behind them,
if we follow the Anatolian agricultural Hypothesis that means that Celts move all the way from Balkans to west/central EUrope and mixed with local Hunters and create the known Celtic culture, a mix of Mediterenean farmers + central/west Europeans Hunters (not Uraloid)
