Darryl is a masculine name with ancient Celtic origins, derived from the Irish name 'Dáire' or 'Daire,' meaning 'fruitful' or 'fertile.' It entered common usage in English-speaking countries as both a given name and surname. Darryl experienced significant popularity in the United States from the 1950s through the 1970s, reaching its peak in the mid-1960s. Sports figures like baseball stars Darryl Strawberry and cultural references in television and film helped maintain the name's visibility. While its usage has declined since its heyday, Darryl retains a friendly, approachable quality.
