I don't believe that Ulanci/Paeonians are descended from Brnjica, Brnjica exclusively cremated their death, unlike Paeonians/Ulanci who used tumuli inhumation burial. That would be weird, when the single basic material culture indicator differs and the timeline is close enough. Brnjica had an influence from Vatin, Gava was closely related to Vatin. I do believe we are looking for E-V13 in Southern Pannonia.
Very likely the Dardanians were a mixture of E-V13, J2b2-L283 and R1b-Z2103, and in order to confirm this we need samples from Early Christian period because Dardanians used cremation and inhumation on their western part where Glasinac-Mat had stronger influence. We see interesting things going on, sometimes Illyrian names appear, but sometimes in the case of Bardylis tribe Peresadyes and his descendand Monunius, these two names appear only among Odrysian Thracians. Something going on there for sure.
Serbian archaeologists grave classification from Timacum samples 2 J2b2-L283 and 1 E-V13-Z5017 indicate that they were either Dardanians or Dalmatians.
Another Naissus sample is E-V13, he was either Dardanian or Triballian.
