Kosenkov

Kosenkov (Cyrillic: Косенков) is a Russian surname. It is derived from the given name "Kosen", which is a short, diminutive form of several Russian male given names, most commonly Constantine (Konstantin) or Kuzma (Cosmas). The suffix "-kov" is a common Russian suffix used to form surnames, typically indicating "belonging to" or "descendant of". Thus, Kosenkov essentially means "descendant of Kosen" or "belonging to Kosen."

Surnames like Kosenkov were typically established in Russia during the period of surname formalization, approximately between the 15th and 18th centuries, initially among the upper classes and gradually spreading to the peasantry. The specific geographical distribution of the surname may provide clues about the family's origins within Russia or other regions with a historical Russian presence.

The surname, like many Russian surnames, can be found in various spellings and transliterations depending on the language and transliteration system used. Variations may include Kossenkov.
