Ciach
Ciach is a common Polish surname. Like many Polish surnames, it likely originated as a patronymic or a nickname.

Another less common theory suggests a connection to the Old Polish word "ciachać," meaning to be lively or cheerful, though this is less widely accepted. The surname is found throughout Poland, with concentrations in various regions. As with many surnames, the spelling and pronunciation can vary slightly in different dialects or historical records. Individuals bearing the surname Ciach have contributed to various fields throughout Polish history and in diaspora communities. Further research into specific family lineages would be required to trace the exact origins and evolution of particular branches of the Ciach family.
