Damonn is of Irish origin, derived from the ancient Irish given name "Dámhan" which means "gentle". It was popularized by the Irish actor, musician, and writer, Domhnall Gleeson, who goes by his anglicized first name Damonn professionally. The name has since gained recognition and usage worldwide due to its association with him.
"Damonn had an equal number of births in two different years (1975 and 1976), with another two years experiencing 5 births each (1997 and 2004). Altogether, there were 22 babies named Damonn born over these four periods."
