Catry / Catherine / Katherine / Kathryn / Katarina / Caitlin

The name Catry is a less common variant of Catherine, which itself derives from the Greek name Aikaterine. The etymology of Aikaterine is debated, but the most widely accepted theory links it to the Greek word 'katharos' (καθαρός), meaning 'pure'. The name gained widespread popularity through Saint Catherine of Alexandria, a 4th-century Christian martyr, whose veneration spread throughout Europe during the Middle Ages.

Over centuries, Catherine evolved into numerous forms across different languages and regions. Catry is a more modern, often diminutive or informal, adaptation. Its usage as a unisex name is relatively recent and less established compared to its feminine counterparts, often appearing as a nickname or a unique spelling choice.
