Meaning:Full of goodness; Man of prayer
Declan is a Irish boy’s name that means “full of goodness,” making it a particularly prescient name for baby. Declan is popular in Ireland because of its association with Deaglán (later Anglicized as Declan) of Ardmore, an early Irish saint who brought Christianity to present-day county Waterford and founded the monastery at Ardmore. St Declan preceded St. Patrick in converting the people of Munster to Christianity, therefore the name also means “man of prayer.” It remains a prevalent name throughout Ireland and the Irish diaspora.
