Derived from Latin origins, 'Decarius' is an uncommon yet distinctive given name. It's derived from the Roman family name 'Decarius', which itself was taken from the cognomen 'Decius'. The latter means 'tenth' or 'belonging to the tenth', perhaps referencing a person who was born in the tenth month of the ancient Roman calendar, or had some other association with the number ten. Historically, the Decii were an important plebeian family during the early Roman Republic. Today, while not widely used, the name Decarius carries a certain unique charm and historical significance.
"Decarius experienced a brief boom in popularity with six babies named in 1992, but it was otherwise quite uncommon that decade, with only five births each in 1991 and 1997. In total, there were sixteen babies named Decarius between those years."
