For Lithuanians and also for Polish Gediminas and his dynasty is the most real royal! We don‘t have any others I am afraid...
Well yes, he was a pagan ruler, so he couldn‘t be given a right to a Christian crown by the Pope.
But Gediminas was a very wise ruler. The ideas of his letters written in XIV century could well read as a XXI century PR action:
„... letters Lübeck, Sund, Bremen, Magdeburg, Cologne and other cities, explaining that the Grand Duchy of Lithuania was very tolerant to the Christians, but remained pagan and did not accept Christianity only because of brutal Teutonic Knights. Gediminas invited knights, squires, merchants, doctors, smiths, wheelwrights, cobblers, skinners, millers, and others to come to the Grand Duchy and practice their trade and faith without any restrictions. The peasants were promised tax exemption for ten years. The merchants were also exempt from any tariffs or taxes.“
