Keivn is of English origin, derived from the Middle English 'Kevin', which itself evolved from the Irish 'Ceiwyn'. The name gained prominence in England during the Norman conquest, brought by the invading Normans who had encountered it in Ireland. In medieval times, Keivn was associated with St Kevin, an Irish saint known for his ascetic lifestyle and miracles. Today, Keivn is a popular choice among English-speaking parents, ranking consistently among the top 1000 boy names in countries like England and Wales.
"Kevin was quite popular as a baby boy name in 1977, with exactly five newborns sharing the name that year."
