In my TL, the ruling house of a reconstituted Bulgarian Tsardom is descended from an Armeno-Byzantine general named John of Priene, who takes the Bulgarian throne as Ivan. I just thought I'd ask on the off-chance anyone knew: what name would his dynasty take? So far, as a placeholder I'm calling them "Prienensis", but I'd like something more accurate if at all possible!
Thanks in advance.
