Meaning and origin of Malachy

Malachy is the anglicised form of the Irish name Maoilsheachlainn (Máel Sechnaill), 'devotee of Secundinus', an early saint. Because it resembled the biblical prophet Malachi, the two names became linked, and Malachy is often explained as 'my messenger'. The best-known bearer is St Malachy, a twelfth-century Archbishop of Armagh and reformer of the Irish church. Later, the 'Prophecy of the Popes' was attributed to him, though historians regard that text as a sixteenth-century forgery.
