Cassily

Cassily is an uncommon name with Irish roots. It is believed to be an anglicized form of an Irish surname, which itself derives from a Gaelic personal name. The Gaelic element 'cas' means 'curly' or 'twisted,' suggesting a person with curly hair. Like many Irish surnames adopted as first names, Cassily carries a sense of heritage and a connection to Irish culture.

The name remains quite rare, contributing to its unique and distinctive feel. Its usage as a given name is relatively modern, likely emerging from the trend of using surnames as first names, particularly in English-speaking countries. While not widely known, its gentle sound and clear meaning give it a quiet charm.
