The early split of Daco-Romanian from the so-called Balkan Sprachbund was already proved by Brian Joseph,and this linguistic reality is also strengthen by the genetics,more precisely the virtual absence of the Greek autosomal component,unlike the Albanians,Aromanians or Bulgarians,etc.
However, this Balkan autosomal ,without a doubt,ultimately represents a closely related element to the Greek one,with a doubt I'm talking here about native DNA.
This leaves little space for the ultra speculated Late Balkanic component that had to be "significant" by many's standards.
But the reality doesn't stop here,in fact the lords with Constanople Greek ancestry had existed with a hundred years before the Phanariote regime,however, they continued the Romanian traditions until the last one,see Constantin Brancoveanu;meaning that even during the Michael the Brave("I leave these mosneni/knezes villages to be freely mastered as they were from the ancient times") ,a lot of villages remained independent, sate cnezesti(knezes ones),where the peasants were called mosneni(basically freemen,see Romanian-Albanian mos(h)).
Among the traditional knezes villages,we find today's highland Arges county,more precisely the old Campulung,Paduret(......Forest County…......)and,of course ,Arges,Vrancea highlands(Old Putnam county),Campulung Moldovenesc area,etc.
