Heladio is of Latin origin, derived from the Roman family name Helladius, which was likely based on the Latin word 'hellus', meaning 'swarthy' or 'dark-skinned'. It is composed of two elements: 'hel-' meaning 'fair' or 'light-colored', and '-adius' meaning 'of' or 'pertaining to'. Therefore, Heladio could be interpreted as 'pertaining to light skin', an ironic contrast considering its likely origin. This name was borne by a 4th-century Christian martyr who was executed during the Diocletianic persecution.
"The name Heladio experienced a slight uptick in popularity between 1991 and 1997, with seven births occurring during this period. However, the frequency of newborns bearing this name has remained relatively consistent over time, with five births each recorded in 1998 and 2011. Overall, there have been twenty-two children named Heladio since 1991."
