No, but your Bosnian cousins claim that they did!
They apparently said that FYROM slavs are Macedonian as well.DNA wise...
No, they said that they were only "30% Antic Macedonian" and the rest is a varying mix.
Me: The first known document written by hand in the Albanian language wasn't even written until 1462 (AFTER Montenegro had acquired its first printing press), which was almost 300 years later than the first accounts in the Serbian language.
This means one of two things -- either that Albanians were one of the dumbest people on the planet, not to have a written language after having been in that location for millenia and being surrounded by those who were literate -- or Albanians didn't exist purely as "Albanians" but as the offshoot or remnants of another culture. Linguistically, that "other culture" was NOT Illyrian. Linguists say that the Albanian language is much closer to an "twisted sistr" offshoot of Thracian with some Latin thrown in.
But that presented a BIG PROBLEM for Albanians claiming Kosovo, because Thracians never inhabited Kosovo, Further Albanians didn't even have any native maritime words that would justify them in the location of modern day Albania with its substantial coastline. In fact, Thracians were from further inland -- as in modern day Bulgaria --where the Bulgarian population is genetically nearly half Thracian.
So the "Illyrian connection" for Albanians was just a convenient lie in order to claim Kosovo from the atheistic Western elite, who worship all things "primitive" and "pre-Christian". Eager to destroy Balkan Christian history with the stroke of pen, phony Albanian claims gave them the excuse.
All we know for sure is that Serbs came to Kosovo in 12-13th century, long after Illyrians, Romans, Bulgars and the Byzantines ruled it. Then we have records of Servs taking Albanian villages to give them to their Church.
Unless you show where the Albanians came from to the Balkans you are stuck.
Regarding the language, you're stuck with a very late slavic one where the 'dumb' Albanians preserved one of the oldest European languages for millenia.
