The personal name Druzha was recorded in 1421 in Southern Bukovina, where a certain Mr. Stroishor Druzha is mentioned. The derivative surname Druskocz is also known, which may be related to the village of Zhdienovo in Transcarpathia.In the 14th century, the male name Druzha was also used among Serbs. M. Grkovich interprets it as a diminutive of the Slavic name Drug or as a variant of the name Druzemir. Additionally, in the Alpine Slavs, the name Druźilubъ was used between the 7th and 14th centuries, and among coastal Slovenes in the 14th century, the name Druśko can be found.
