Giorgi Dadiani is also known from undated inscriptions, in the Georgian asomtavruli script, from the territory of Odishi, which allow reconstruction of his genealogy.
He was a son of mandaturt-ukhutsesi ("Lord High Steward") Bediani-Dadiani by his wife Khuashak, daughter of Bega, eristavi of Kartli, and had two brothers, Ioane and Erashahr.
[1] Giorgi is depicted in a fresco on the northern wall of the Khobi Cathedral, his own foundation, with a model of the church in his hands.
[2] Giorgi Dadiani held sway over his patrimonial princedom of Odishi, latter-day Mingrelia, in the time when the Kingdom of Georgia, under the heavy-handed hegemony of the Mongol Ilkhans, suffered political division and was embroiled in a series of internecine feuds.
Its western moiety, Imereti, of which Odishi was part, had also been fighting its own civil war between the successors of King David Narin—Constantine and Michael.
