Pllease excuse the following it is only a draft, very rough and probably contains numerous errors.
Please note that I put the Georgian Dukes in as Princes because Russian "Light Princes" seemed to have reigned over little more than a single town, whereas the georgian duchies were significantly more than that. Some times incompassing 9 or more towns
