Are Assyrians from Bohtan descended from the Tyari?

I'm mostly Assyrian, primarily from the Bohtan region (2/4 Gaznakh and 1/4 Harbole, the other 1/4 is armenian), and my father was telling me about how his father used to claim to be Tyarnaya, or like descended from them. I can't really find anything about it online do anyone know anything about Bohtan lol there doesn't seem to be much information about us.
