Kilean is of Irish origin, derived from the ancient Irish name Cillíín. It means "devoted to God" or "church". The name was traditionally given to a boy born around Christmas time, but it is now used throughout the year. In the 19th century, Kilean was considered one of the most popular boys' names in Ireland. However, its popularity has since declined, making it quite rare today. Despite this, it remains a unique and meaningful choice for parents looking for an unusual name with a strong historical background.
