Yefimovicha
Yefimovicha is a common patronymic in Eastern Slavic cultures, particularly among Russian and Ukrainian speaking populations. It is derived from the male given name Yefim (or Yefimiy), which itself originates from the Greek name Euthymius, meaning "good-spirited" or "well-disposed." In the patronymic system, the "-ovicha" suffix indicates a male offspring. Therefore, Yefimovicha literally translates to "son of Yefim."
This patronymic is typically used in conjunction with a given name and, in some contexts, a surname
