Show ContentsKasimir History, Family Crest & Coats of Arms

The Polish surname Kasimir derived from the words "kazic," meaning " to spoil or destroy," and "mir," meaning "peace." From these words, it became both a given name and a place name (Kazimierz, North East of Cracow), and in turn was adopted into a surname from both these sources.

Early Origins of the Kasimir family

The surname Kasimir was first found in Polesie, the largest province of Poland. It is inhabited by Ruthenians, called Polesians, of Ukrainian descent. This name was a popular name with Polish royalty in the times before surname usage had begun in Poland, beginning with Duke Casimir the Restorer in 1015-1058. Kobryn was the seat of the Kazimierowski family. The surname became noted for its many branches in the region, each house acquiring a status and influence which was envied by the princes of the region. In their later history the name became a power unto themselves and were elevated to the ranks of nobility as they grew into this most influential family.
