History & Origin

Casimira feminizes Casimir (Polish Kazimierz), whose Slavic parts are variously read as 'destroy' and 'peace' — either 'destroyer of peace' or 'proclaimer of peace'. Polish and Spanish-speaking Catholic families carried it to the United States.

It saw its faint high point in the early twentieth century around 1916 and held on in small numbers into recent decades. Only a few dozen girls a year ever carried it.

Did you know? The male Casimir was borne by Polish kings and by Saint Casimir, patron of Poland and Lithuania, giving the feminine Casimira a deep Central-European Catholic backdrop.
