Cecilia is a feminine given name of Latin origin derived from the Roman family name Caecilius, which means "blind". It has been popular throughout history and across different cultures, notably due to Saint Cecilia, a 2nd-century Christian martyr whose feast day is celebrated on November 22nd. In England, the name began appearing in records as early as the 12th century and remains popular today, with variations including Cecile, Cece, Cici, and Zelie.
