Kleshchin

Kleshchin (Клещін) is a Russian surname. It is derived from the word "kleshch" (клещ), meaning "tick". Surnames derived from animals or insects were not uncommon in Russia, often reflecting a perceived characteristic or association. In this case, the surname might have originated as a nickname for someone considered persistent, clinging, or troublesome, although the specific origin and intended meaning associated with the initial bearer are difficult to determine with certainty without genealogical records. The surname likely first appeared during the period when surnames began to be formalized in Russia, around the 15th-17th centuries. Variations in spelling, such as Kleschin or Kleshin, might also exist due to transliteration differences or regional dialectal variations.
