How to Pronounce Keaghan
Pronounced KEE-guhn /ˈkiːɡən/High
Meaning: Keaghan is a decorative respelling of Keegan, the Anglicised Irish surname Mac Aodhagain, 'son of Aodhagan'. That name is a diminutive of Aodh, the name of a Celtic fire god, so Keegan and its variants are usually read as 'little fiery one' or 'descendant of Aodh'. The Irish-looking -agh- cluster in Keaghan adds visual heritage without changing the plain 'kee-gun' sound.Medium

History & Origin
Keaghan reworks Keegan, from Irish Mac Aodhagain and ultimately Aodh, 'fire'. The added -gh- gives it a more Gaelic look while keeping the familiar sound. It rode the same early-twenty-first-century taste for Irish surname-names that lifted Keegan, Declan and Rowan.
The fancier spelling stayed rare: Keaghan drew only a couple dozen boys a year even at its high around the end of the two-thousands, well behind plain Keegan. A boy given it is still young, from the cohort when Irish surname-names and inventive spellings were both fashionable.
