Meaning & origin
Demarrio is a modern coinage that first appeared in U.S. birth records in 1976, a time when distinctive prefixed names were gaining popularity. It reached its highest usage in 1984, though it remains unranked nationally. The name combines the fashionable prefix De- with a Mario-like ending, reflecting the creative naming trends of African-American communities in the late 20th century. While Demarrio never achieved wide adoption, it has maintained a stable presence, appearing each year through 2025. Its top states of use are not well-documented due to its rarity, but it fits a pattern of similar names like DeShawn and DeAndre. Demarrio's meaning is ultimately invented, and as such it carries the personal significance given by its bearers.
