In 2008 I was in a Pyrenean Ski resort enjoying the atmosphere of a crowded bar. The choice of music, which fearured bagpipes, drums and a small harp, giving an almost gaelic feel to the evening. Suddenly I realised that the conversation bouncing around me was not French but Occitan!
For those who visit the area it is probably enough to say that the inhabitants of Occitan are unique vibrant and proud.
Ethnicity

The net result that is that there are significant differences of opinions.
Language
Language has traditionally been used to distinguish between different peoples and different ethnicities.
There are four major languages which emphasise the differences in what is now France; Breton, Basque, Francais (Langues d’Oil) and Occitan (Langues d’Oc).
Breton is a Celtic language with strong similarities with Cornish and Welsh, It is generally accepted that the Bretons arrived from Cornwall and that they were Atlantic Celts fleeing from the Anglo Saxon invasion of Britain.
Français is basically a German, not Celtic language. Le Francais (Langue d’Oil) was derived from Frankish influenced by Latin but there are hundreds of words which linguists consider to be Celtic, which passed into French after first being being absorbed into the form of Vulgar Latin spoken in Northern France.
In a similar way Occitan (Langue dOc) is derived from Latin but the non Latin roots are not Germanic or Celtish, but some other Language, possibly Basque.
However just to complicate matters there are speakers of an Occitan dialect in Northern Italy and in the Val d’Arana in northern Spain. There are strong similarities to the Catalan language and culture of North Eastern Spain.


One theory is that with the onset of the Ice Age, what is now the Basque country, Aquitaine and Occitanie became a refuge for an earlier people driven south. They spoke a language (called here Aquitainii) spoken on both sides of the Pyreneees. This language was not Indo-Euopean. Two other languages; Iberian and Tartessian were also pre Indo-European.
These languages were still spoken at the time of the Roman invasion but at that time in the middle of the Iberian peninsula there were Celtic Tribes including the Lusitanians who did speak an Indo- European language.
There is much discussion, but no agreementas to wether Aquitanii is a precursor to Basque or a devevelopment of it.

What seems to be certain is that the Basque language or it’s predecessors once covered a much bigger area. Basque must have survived undiluted in the Western Pyrenees and along the coast of the Bay of Biscay because, whatever the history books say, it was never absorbed into the Roman Empire. Basque has gradually retreated to this relatively small area at the base of the Western Pyrenees
What all these thories have it in common that the language spoken in Aquitaine, Occitan and Provence and therefore the ethnicity of it’s people is completely different.
Dialects

There are at least seven dialects of Occitan.
The Celts

50 years ago when the other source of determination of ethnicity was archeologists. it was generally assumed that after the demise of the pre Indo-Europeans , Celtic civilisation covered the whole of mainland europe with the small exceptions of Etruscans, Romans, Carthagenians and Greeks. However this diagram, though drawn from a site promoting celtic heritage shows the significant greek (Magna Greacia) presence in what today is Provence-Alpes-Cote d’Azur (PACA).
The Celts are popularly believed to have sprung from a people from Hallstatt in Austria. Conclusions about their spread are still mainly based on the archeological discovery of Celtic artefacts in the areas shown.
Differences in the syle of artefacts discovered indicate different cultures , such as the “Hallstadt” or “La Tene” cultures, often defined by differing styles of building, burial, jewellery or domestic utensils.

There is evidence however of some selectivity with regard to the artefacts chosen to illustrate the achievements or level of sophistication of the cultures studied.
The “golden shoes” discovered on one of the “la Tene” sites give a totally different perspective on who the “ la Tene” people were to the image projected by the more common displays of prosaic “la Tene” artefacts.
These are not “shoes” they are ‘foot decoration’.

Note, however that this more recent graphic does not show the Celts as occupying the area of Aquitaine or Occitaine.
Thus, by this information alone, the peoples of Greater Occitan are different from the French north of the Central Massive.
The Roman View

The Roman provinces established to govern these peoples allowed for these differences.
This grapic also shows the area along the mediterranean coastline called Provincia Narbonensis. Caesars gallic wars originated to protect the Greek settlements in this are from celtic attacks.
Later this area became known as “Septimania” because of land grants in the area given to retired soldiers from the Seventh Legion. It includes the areas of both Occitanie and Provence-Alpes-Cote d’Azure (PACA).
Against the Ocean

Barry Cunliffe (Barrington Windsor Cunliffe), Emeritus Professor of history at Oxford, has a rather different view expressed in his books Against the ocean and Ancient Celts.
He believes that some Celts origated along the Atlantic coastline and from there spread into the european mainland.
Certainly the view from the Atlantic gives a totally different perspective of the relation of the lands facing the ocean and of the position of Aquitaine and Occitan.
Genealogy
The analysis of Human DNA is a newly emerging science which is in a stage of accelerating growth, due to the fact that the same basic technique can be used for a number of different purposes.
In forensic investigations it can help identify the perpetrator of a crime. In medicine, research showing our genetic make is being linked to a predilection to certain illnesses. It can therefore assist in the cost effective targeting of preventative care.
It can also tell us much about our heritage.
Inheritance

The two versions of DNA inherited from parents have distinctive markers called STR’s (Short Tandem Repeats). A child’s STR pattern will include both the parents STR’s. These markers can help pinpoint parents or grandparents of a child. STR’s however become unreliable beyond that as the mutations change relatively frequently and can reverse.
XY Pairing

The XY Pairing is quite different. Each male child receives an X chromosome from the mother and a Y chromosome from the father. Over the history of Homo Sapiens, the X and Y chromosomes have experienced two kinds of genetic mutation. STR’s occur as they do in other sections of the DNA, and are similarly relatively transient. In the XY pairing another mutuation occurs SNP’s(Single Nucleotide Polymorphism) or “snips”
Tracing Ancestors
SNP mutations happen infrequently and do not reverse. For males analysis of the structure of the Y chromosome makes it possible to trace back male ancestors for tens of thousands of years and to identify which tribe the person belongs to. The scientific name for “tribe” is Haplogroup.
DNA Discrimination
A female child however receives an X chromosome from both father and mother but no Y chromosome . It is not possible therefore to trace a woman’s patrilineal heritage directly. It can be traced through the Y DNA of a father, brother or uncle, assuming those relationships are firmly established.
Mitochondri

All of us, male and female, also carry, independent of the chromosomes in the nucleus of each cell, a material called Mitochondri. It is the material which enables cells to use the energy generated from food. It has its own independent, stable DNA and it is only inherited from our mothers. The Mitochondri therefore permits the tracing of our matrilineal heritage.
This tracing is possible for both men and women without a need to use relatives as a reference
Tracking our ancestors
Geneologists have, in the twenty-first century, played an increasingly important role in defining ethnicity, supplementing much of the work previosly carried out by archeologists and linguists.
It centers around the distribution of occurances of human mutations in modern populations. It gives an alternative view of themovement of peoples.
Human DNA has mutated many times. starting with Haplogrop A, carried by the ancestors of homo sapiens as they came out of Africa.
The original Haplogroup was called A (for Adam) and all major subsequent mutations have been contained within the twenty six letters of the alphabet
DNA Haplogroup T-An Earlier people

It is not, however, a good match for Aquitaine, Occitaine and the Basque country. There is a relatively low level of T in this areas, not what would have been expected if this is where the pre Indo-Europeans had founf refuge from the ice age . How can a pre Indo-European language have persisted until the 21st century when there is a low incidence of what is promoted as the pre Indo-European haplogroup ?
It could have been that the pre indo Europeanns (Vascones?) came from a totally different Haplogroup. Y DNA E has been suggested but that is not a good match either.
The Mating Game.

There is another explanation. Women in their search for security for their children will give powerful wealthy men preference. Their children would then be in demand, both male and female, because they had access to influence procured by wealth and power. It is an interesting example of natural selection.
The pattern of the XY chromosome inheritance means that the latest pairing in a genetic chain wipes out all evidence of all earlier pairings.
Assuming that the T1 men were dispossessed or driven out by R1b men, their DNA may be lost but through their woman folk the language could be retained.
In a society where control of sexual activity and family life lay with the women, and that seems to have been true of this area, this is not only possible but probable.
DNA The Dominance of Rb1

It seems certain that the earlier Haplogroup was displaced by Various mutations of the Rb1 Haplogroup. Rb1 is one of the major genetic mutations in male members of the human race. It is the most common mutation in western europe and in particular on the Atlantic seaboard. At first glance this supports Professor Cunliffe’s theories and at the same time undermines any concept that the peoples of Occitan are in some ways unique. R1b is everywhere!
R1b is however is still a relatively early mutation. There have been many other mutations scince.
DNA ALL R1b 1a 1a 2

This is an early mutation of R1b which has been gven the name M269. It is spead even more evenly along the Atlantic coast than the total Rib, This mutation is famous for the fact that Tutenkamun may well have been a member of the group sharing it. Again the implication seems to be that there is nothing unique about Occitanie. M269 based genes did occur in Occitan and Aquitaine and the people who shared this gene may well have been the original Atlantic Celts.
DNA The Atlantic Celtic Gene

There are however still more subsequent mutations, which when isolated, tell a very different story. L21 is one of these. The chances are that the mutation took place in Northern Ireland. Its ‘long name’ is R1b 1a 1a 2.
Perhaps influenced by the Cunliffe theories genealogists have now identified L21 as the “fingerprint” of Atlantic Celts. This totally changes the picture. There is a very low incidence of this “Celtic gene” in the area of Aquitane and Occitaine.
DNA Longnames

To answer the question , it is necessary to have an understanding of the sequence of mutations.
The original naming convention devised in the late 20th century made it possible to do this. Successive mutations were “tagged onto” the earlier mutation.
Initially the award of seondary titles to regognise the research organisation and the individual researcher who first isolated the mutant gene, was a little piece of scientific arrogance but not serious. It became annoying when competitive laboratories started giving their own name to haplogroups which had already been discovered.
I am not the only person to think that the naming of Haplagroups is now a total misleading mess! Practitioners plead that genealogy is an exact science but the naming conventions are anything but.
In 2006 the first year that ISOGG compiled a SNP tree, the number of Y DNA haplogroups was around 400 not the tens of thousands which have been identified since, No one would ever have believed this SNP tsunami would happen, let alone in such a short time.
CeCe Moore, an independent professional genetic genealogist says:-
“I have to admit that when R1b1b2 was changed to R1b1a2, I just started saying “R1b…whatever” when referring to it. Isn’t it easier to just remember the defining SNP name R-M269?
For example, if you are R-L21+, then according to Family Tree DNA’s Haplotree, you are R1b1a2a1a1b4, the ISOGG 2011 Haplogroup Tree’s name for it. At 23andMe, you are R1b1b2a1a2f in agreement with the 2010 ISOGG Haplogroup Tree.If you tested in 2008, you might still think you are R1b1b2a1b6. On ISOGG’s 2011 Haplogroup Tree , L21+ was R1b1a2a1a1b4, buton ISOGG’s 2012 Haplotree, you are R1b1a2a1a1b3. Apparently, R1b1a2a1a1b4 is now referring to L238/S182! I mean, really, how can anyone keep track? (Ah, for the days of the simple little R tree.) I don’t know how our ISOGG Haplogroup Tree Committee does it anymore! Apparently, the academics are getting tired of it too and it’s just going to get worse when results from Geno 2.0 start rolling in with LOTS of new SNPs and subclades being defined.
Take look at the history of R-M222, the “Ui Niall Subclade”, on just the ISOGG SNP Tree:
2007 = R1b1c7
2008 = R1b1b2a1b6b
2009 = R1b1b2a1a2f2
2010 = R1b1b2a1a2f2
2011 = R1b1a2a1a1b4b
2012 = R1b1a2a1a1b3a1a1Reportedly, Geno 2.0 will define at least three new subclades beneath M222, but I hear it may be more. Do you think those subclade names might get even longer?”
The above is an extract from an article favouring the use of the short names. which igrores the problem of there being several different short names for the same Haplogroup. The problem with only using the SNP names, which are created by the laboratory which first isolated the gene is the SNP names have no meaning other that giving recognition to the researcher. It is only by having the long names that sequencies of mutations can be deuced. If only the SNP names are used then only the specialists will be able to understand sequencies and there is evidence that they will occasionally get it wrong, perhaps even coming to “politically correct” or “commercially advantageous” conclusions.
All the longnames in this diagram are from the ISOGG naming convention of 2011 not the later versions. It should make no difference as long as all longnames are from the same convention, but there are inconsistencies.
DNA Topographical Interpretaion of the Longnames

Only one of these, S28 can be the parent of the L21 Mutation. Thus the Pyrennean mutation M47 has no involvement in the Atlantic Celtic mutation.
DNA The Pyrennean Gene

DNA The Hallstat Gene

DNA the German Gene

The relatively low incidence of S21 in the most of what is now France confirms previous ideas that the Franks simply took over the Roman state but did not replace it.
Genetic conclusion
Thus from a genetic point of view Occitiane are not only relatively unique, but quite different from the Franks, which is what they claim, proudly and insistantly.
