He models good as 3/4 Talysh + 1/4 Persian of some sort. Could also be Tat, maybe? The name provided sounds kind of atypical for a Persian in general, to be honest.
I doubt he would have North Caucasian ancestry. Muhajirs and other deportee's were settled along Mazandaran shores except for a couple cases. They were mostly ethnic Georgians and Circassians, and he is not fitting too well
