I heard about these 3rd branch of Aryans. Can you tell us more about them? Where did they originated and which Indo-Aryan dialects are closest to it?
Tocharians are not the same as Tukhara. The people of the Tarim Basin were incorrectly named "Tocharian". But anyways, what makes you say the Tocharians were Aryan? Aryan has always meant Indo-Iranian.

Bactrian (along with Greek) was one of the official languages of the Kushan Empire. It had nothing to do with the "Tocharians" of the Tarim Basin.

Yes they were. I didn't pay attention to what he meant by "ABC". My point is that the Tocharians mentioned in history (Tukharas) are the original Tocharians and they were ethnic Bactrian. The people from the Tarim Basin are not Tocharians at all though but just wrongly given that name. But they were also IEs.
