Origin of Bronze Age IE settlers in the Balkans

[xripkan]

The exact origin of Balkan settlers is not known yet but what is suggested? I have read that Proto-Thracians and maybe Phrygians are connected with Multi-cordoned Ware culture (R1a), a successor of Catacomb culture. They had many interactions with Srubna culture (R1a-Z93), so I suppose a number of Proto-Thracians was R1a-Z93 like the Bronze Age Bulgaria sample. Proto-Myceneans are considered descendants of the Catacomb culture of the Pontic steppes (mostly R1a). On the other hand Dorians and Illyrians were mostly R1b. Do they connect to Bell Beaker culture?

Yes, I know that Myceneans brought a lot of J2 lineages from Caucasus but they had also steppe ancestry so some of them had definitely haplogroups R1a and R1b. The sample from Bronze Age Bulgaria was autosomally identical to Srubna culture though.
