Originating from Ireland, the name Flinn is derived from the Irish surname 'Ó Fhloinn', which was once one of the most common surnames in County Mayo. Historically, it was an anglicized form of the Gaelic 'Ó Dhomhnaich' meaning 'descendant of Domhnach'. Domhnach itself comes from the Old Irish 'Domnac', a personal name derived from the word 'domhan', meaning 'world'. Therefore, Flinn is essentially a surname that has evolved into a given name, bearing a rich historical and cultural heritage.
"Flinn saw a notable increase in babies named after it, with only five newborns sharing the moniker in 2020, but seven coming into the world in just two years later, totaling twelve little Flinns."
