Meaning & origin
Casmer is a rare masculine name first recorded in the United States in 1911, the same year it reached its peak usage. Since then, it has maintained a stable but extremely low profile, with no recorded rank in recent years. The name is likely a variant of the Slavic name Casimir, which carries a hopeful meaning of 'proclaimer of peace.' In the 1910s, Casmer saw limited use, primarily among families of Polish or Slavic heritage. While no states show a significant concentration, the name reflects a tradition of honoring patron saints and royal figures from Eastern Europe. Today, with a one-in-N ratio too high to calculate, Casmer remains a distinctive choice for parents seeking a name with historical depth and rarity.
Casmer is likely a variant of Casimir, from the Polish Kazimierz, derived from Slavic elements kaziti 'to destroy' and miru 'peace', thus meaning 'destroyer of peace' but historically interpreted as 'proclaimer of peace'. The name was borne by several Polish royals and saints. Casmer appears as an anglicized spelling, recorded in the United States since the early 20th century.
