Küllisäär

Küllisäär is a relatively uncommon Estonian surname. Its etymology likely derives from a combination of Estonian words. The first part, "Külli," is a common Estonian female given name, a diminutive of names such as Kyllikki. The second part, "säär," translates to "shank" or "leg" in Estonian.

Therefore, the surname could potentially refer to someone associated with a woman named Külli who was known for her legs, or perhaps it originated as a nickname with a more figurative meaning. However, without specific historical records or genealogical information pertaining to the family bearing this surname, the precise origin and intended meaning remain speculative. The name is geographically dispersed within Estonia, without a strong concentration in a particular region. Individuals with this surname can be found in various sectors of Estonian society.
