The Raetians might have something to do with it. They appear as one of the most powerful alpine tribe according to several text. Some scholars have linked their language to Etruscan. It seems that with the arrival of Cisalpine Gaul circa 400 BC they moved northward. The Imperial province of Raetia in the Roman empire included switzerland, Tyrol and a German part south of the Danube.
Also around the Alps, there is hotspot of Haplogroup G
Good point.
From what I can see based on list of important cities
http://en.wikipedia.org/wiki/Raetia
Raetia included Swiss, complete south Germany (not just soutwest Germany) and north Italy, west most part of Austria....
in fact, this makes me wonder whether alternative name of Serbs (Rascians see
http://en.wikipedia.org/wiki/Raci and
http://en.wikipedia.org/wiki/Rascia) may in fact origin not from some link with Etruscans but from being in most east parts of Raetia province
historical source Byzantine emperor claims that Serbs settled Balkan from white Serbia which they call Boika (which likely has meaning land of Boii) where they originally dwelt... according to his words this land of Boika is beyond Hungary (called Turkey by Bizantine historians due to Hun and Avar settlements as this was all much before Turks settled in Asia minor) and neigbours Francia and white Croatia...this all points to Bohemia which is named after Boii tribe...
The Serbs are descended from the unbaptized Serbs, also called 'white', who live beyond Turkey in a place called by them Boiki, where their neighbour is Francia, as is also Great Croatia, the unbaptized, also called 'white': in this place, then, these Serbs also originally dwelt. But when two brothers succeeded their father in the rule of Serbia, one of them, taking one half of the folk, claimed the protection of Heraclius, the emperor of the Romans, and the same emperor Heraclius received him and gave him a place in the province of Thessalonica to settle in, namely Serbia, which from that time has acquired this denomination....

Bohemia is hotspot of I2a2
Strabo among people of Bohemia also names Sibini..
Here, too, is the Hercynian Forest,15 and also the tribes of the Suevi, some of which dwell inside the forest, as, for instance, the tribes of the Coldui,16 in whose territory is Boihaemum,17 the domain of Marabodus, the place whither he caused to migrate, not only several other peoples, but in particular the Marcomanni, his fellow-tribesmen; for after his return from Rome this man, who before had been only a private citizen, was placed in charge of the affairs of state, for, as a youth he had been at Rome and had enjoyed the favor of Augustus, and on his return he took the rulership and acquired, in addition to the peoples aforementioned, the Lugii (a large tribe), the Zumi, the Butones, the Mugilones, the Sibini,18 and also the Semnones, a large tribe of the Suevi themselves. However, while some of the tribes of the Suevi dwell inside the forest, as I was saying, others dwell outside of it, and have a common boundary with the Getae.19 Now as for the tribe of the Suevi,20 it is the largest, for it extends from the Rhenus to the Albis;
quoted from
http://www.perseus.tufts.edu/hopper...999.01.0198:book=7:chapter=1&highlight=sibini
So, in Strabo's time Marcomanni (or people led by Marabodus) rule over Bohemia and over several tribes among them large tribe Luigii and also Sibini
Sibini could be a tribe of proto-Serbs that might have later departed for Balkan, as in Serbian language a word for a Serb is "Srbin" ... while Luigi is likely about Lugii who may later gave people known as Lusatians/Sorbs/Wends
now, back to Rhaetia
if we look
closest Raetian town to Bohemia, its name is
Sorviodurum today Straubing (
http://en.wikipedia.org/wiki/Straubing)
thus, Serbs lived in east most part of Raetia which partly overlapped with Bohemia, but were not Raetians (G haplogroup and different language)
this is explainable by Vindelicia being added to Raetia province in 1st century AD....
At first Raetia formed a distinct province, but towards the end of the 1st century AD Vindelicia was added to it; hence Tacitus (Germania, 41) could speak of Augusta Vindelicorum (Augsburg) as "a colony of the province of Raetia". The whole province (including Vindelicia) was at first under a military prefect, then under a procurator; it had no standing army quartered in it but relied on its own native troops and militia for protection until the 2nd century AD.
http://en.wikipedia.org/wiki/Raetia
Vindelici name is related to Celtic word "white", while if you look up in Byzantine source Serbs of Bohemia were also called "white"...
Vindelici is obviously related to Vind/Veneti tribal name...
Venetoi = latin wind gods
Wend = Germanic word for Sorbs and Slavs in general
Jordanes indicates that early Slavs are populous race of Veneti
in the land of Scythia to the westward dwells, first of all, the race of the Gepidae, surrounded by great and famous rivers. For the Tisia flows through it on the north and northwest, and on the southwest is the great Danube. On the east it is cut by the Flutausis, a swiftly eddying stream that sweeps whirling into the Ister's waters. (34) Within these rivers lies Dacia, encircled by the lofty Alps as by a crown. Near their left ridge, which inclines toward the north, and beginning at the source of the Vistula, the populous race of the Venethi dwell, occupying a great expanse of land. Though their names are now dispersed amid various clans and places, yet they are chiefly called Sclaveni and Antes. (35) The abode of the Sclaveni extends from the city of Noviodunum and the lake called Mursianus to the Danaster, and northward as far as the Vistula. They have swamps and forests for their cities. The Antes, who are the bravest of these peoples dwelling in the curve of the sea of Pontus, spread from the Danaster to the Danaper, rivers that are many days' journey apart. (36) But on the shore of Ocean, where the floods of the river Vistula empty from three mouths, the Vidivarii dwell, a people gathered out of various tribes. Beyond them the Aesti, a subject race, likewise hold the shore of Ocean.

I have already shown that spread of early Slavs does match spread of I2a2 and not of R1a.... and gave other clues that Veneti (who origin from Paphlagonia Eneti who were kicked out of Asia minor after Troyan war) were I2a2...
now, this is all in accordance with known facts about Vindelicia
The material culture of its inhabitants the Vindelici was La Tène. The ethnic origin of the Vindelici is not sure. Whether they spoke a Celtic (i.e. Gaulish), Germanic, or other Indo-European language is unclear. (A possible etymology of their name includes a Celtic element *windo-, cognate to Irish find- 'white'.[1]) However, according to a classical source, Servius' commentary on Virgil's Aeneid,[2] the Vindelicians were Liburnians, themselves most probably related to the Veneti.[3][4] (A reference in Virgil[2] seems to refer to the Veneti as Liburnians, namely that the "innermost realm of the Liburnians" must have been the goal at which Antenor is said to have arrived.) Thus, it seems that the ancient Liburnians may have encompassed a wide swathe of the Eastern Alps, from Vindelicia, through Noricum, to the Dalmatian coast.

Interesting - Etruscans called themselves Raesena or Rasenna, so that is not far off from the Raetians, which would be our name for them. The Raetians name for themselves could very possibly be closer or even the same. I would like to see more on this.
Raetians are considered related to Etruscan
Little is known of the origin or history of the Raetians, who appear in the records as one of the most powerful and warlike of the Alpine tribes. Livy states distinctly[1] that they were of Etruscan origin (a belief that is favored by Niebuhr and Mommsen). A tradition reported by Justin[2] and Pliny the Elder[3] affirmed that they were a portion of that people who had settled in the plains of the Po and were driven into the mountains by the invading Gauls, when they assumed the name of "Raetians" from an eponymous leader Raetus; a more probable derivation, however, is from Celtic rait ("mountain land"). Even if their Etruscan origin be accepted, at the time when the land became known to the Romans, Celtic tribes were already in possession of it and had amalgamated so completely with the original inhabitants that, generally speaking, the Raetians of later times may be regarded as a Celtic people, although non-Celtic tribes (Lepontii, Euganei) were settled among them.
