Meaning & origin

Bacilio first appeared in U.S. records in 1922, a year that also marks its peak usage. Since then, the name has maintained a stable but extremely low profile, never reaching even one birth per million in any recent year. With no recorded births in most years and no concentration in any particular state, Bacilio remains a highly unusual choice. Its trajectory has been flat for over a century, making it a true rarity. Parents who choose Bacilio are selecting a name with a distinguished heritage via its connection to Basilio, yet one that has never gained traction in American naming culture.

Bacilio is a rare given name of Spanish origin, likely a variant of Basilio. Basilio itself derives from the Greek name Basileios, meaning 'royal' or 'kingly'. The name saw minimal use in the United States, with only a handful of recorded instances in the early 20th century.
