History & Origin

Casmer is a trimmed American spelling of Casimir, Polish Kazimierz, from Slavic roots read as 'to destroy' plus 'peace'. Immigrant families brought it to the United States, where it was often simplified.

It was always rare - only a few dozen boys a year at its high point around 1918 - and its recorded use faded within a couple of decades. It reads as a Polish-American heritage name.

Did you know? Casimir was borne by Polish kings and by Saint Casimir, patron of Poland and Lithuania, which kept the name alive among Polish-American families.
