Name «Diadko»

"Diadko" is a rare Slavic name that derives from the Ukrainian term for kinship "дядько," meaning 'brother of the father or mother; husband of the aunt' (Ukrainian Language Dictionary, Vol. II, p. 450). The first mention of the personal name "Diadko" dates back to 1241, when it was recorded in Kyiv in the form "Дядъков градъ" (Electronic Dictionary of Old Ukrainian Language, p. 58). For instance, in 1491 it is mentioned: "our servants Niegоe Orbєskoul and their brother Dядко and Vlad" - in the city of Suceava (Dictionary of Old Ukrainian Language, Vol. I, p. 341). There is also the patronymic "Diadkovych," recorded in 1289: Semyon Diadkovych - boyar of Kholm, envoy of Lev Danilovych (The Chronicle of Rus', p. 449). Another mention is from 1404 - Gleb Diadkovych - in the city of Medika (Dictionary of Old Ukrainian Language, Vol. I, p. 342).
