Kazimiera is from the Polish Kazimiera — feminine of Kazimierz from Old Polish kazić (to destroy) + mir (peace) — famous destroyer of peace, destroyer in battle. Kazimiera is one of the Polish feminine names — central to traditional Polish Catholic heritage. Polish feminine name reflecting Polish Catholic heritage.
Kazimiera does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Kazimiera reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
