Kloos

Kloos is a surname of German origin. It is found in Germany and among people of German ancestry around the world. The name is thought to be derived from a given name such as Klaus or Nikolaus, or possibly from a descriptive nickname or a place-based term in Middle High German, though exact origins may vary by family. Variants include Kloos with a double o, Kloss, Klaus, and Klous, the latter reflecting regional spelling differences before standardization. The surname is relatively uncommon, but records show its presence in central and southern German-speaking areas and in diaspora communities in North America and elsewhere due to emigration in the 19th and 20th centuries. In onomastic studies, Kloos is treated as part of the broader family of patronymic and nickname-derived German surnames linked to the given name Klaus or Nikolaus.
