Klara is the Slavic, Scandinavian, and Hungarian form of Clara — from the Latin clarus (clear, bright, illustrious). Klara Sesemann — central character of Johanna Spyri's Heidi (1880-1881); the wealthy invalid Frankfurt girl who becomes Heidi's best friend; Heidi has sold 50+ million copies worldwide and been translated into 70+ languages; one of the bestselling Swiss novels of all time. Klara Wójcik — Polish historical figure. Klara Söderberg — half of the Swedish folk duo First Aid Kit (with sister Johanna Söderberg); the duo has released 5 studio albums and toured internationally with Bruce Springsteen and Conor Oberst. Klara Smith — modern American figure. Klara Reichard — German actress.
Klara 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 Klara reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
