Demario

Demario combines the prefix 'De-' with 'Mario.' Mario is derived from the Latin name Marius, which may have originated from Mars, the Roman god of war, or possibly from the Latin 'mas' meaning 'male.' The 'De-' prefix is a common addition in modern American naming practices, possibly influenced by French, Italian, or Spanish naming traditions where 'De' often indicates 'of' or 'from.' Demario emerged in the United States during the mid-20th century and saw increased popularity during the 1970s-1990s. The name appears across diverse communities but has been particularly documented in southern states. Some variations include De'Mario or DeMario, with different styling of the prefix. The name exemplifies how traditional names are often modified with prefixes to create distinctive variations.

Demario is also given to girls.
