Sille

Sille is a Danish feminine name that developed as a vernacular short form of Cecilia, itself derived from the Latin family name Caecilia, which is connected to the Roman clan name Caecilius and possibly related to the Latin caecus, meaning blind. The name gained popularity in Scandinavia through the veneration of Saint Cecilia, the early Christian martyr and patron saint of music. Related forms include Silje in Norwegian and the fuller Latinized Cecilia found across much of Europe.
