kiil

Kiil is a surname of Estonian origin. In Estonian, kiil means wedge, a tool or wedge-shaped piece used in carpentry and masonry. As a surname, Kiil is thought to have arisen as an occupational nickname or a toponymic element, though precise historical derivation is not widely documented in available sources. The name is relatively uncommon and is most frequently found in Estonia, with bearers also appearing among Estonian communities abroad.

The distribution of the surname Kiil is primarily intra-national, reflecting its Estonian roots. It is encountered in genealogical and civil registry records, and bearers may be found in regions with historical Estonian populations or diaspora communities.

Notes on usage and recognition: Kiil does not have a widely documented history of prominent, internationally recognized individuals tied to the name in major reference works. As a result, the surname is most often noted in regional or genealogical contexts rather than in global biographical references.
