^Al-Jazira and Aleppo had their own branches, but under their first two coin-issuing rulers, they did have a “joint coinage”. I believe a general “Hamdanid dynasty” would work, although it might more accurately be “Al-Jazira and Aleppo” to reflect the fact that these separate areas had a joint coinage system. Up to you. :)
