Cecelio is of Latin origin, derived from the Roman family name Caecilius, which was believed to have been derived from 'caecus', meaning blind. The name gained popularity during the Middle Ages due to St. Caecilius, an early Christian martyr. Cecelio is often associated with the Italian language and culture, as it is more commonly used in Italy than other countries. It is typically pronounced /tʃeˈtʃɛlio/ in Italian, with the stress on the third syllable. In the English-speaking world, this name may be spelled variations such as Cecilio or Cecilia for males and females respectively. Despite its Latin roots and Italian association, Cecelio has not been widely adopted into the English naming tradition.
"Cecelio is an uncommon name, with only two recorded births in total over four decades - five in 1929 and another five in 1969."
