Insights

Today, Declan is a popular, familiar name (popularity 82/100).

It is less common today than at its historical peak.

Declan is an Irish name derived from the Old Irish name 'Deaglán,' which is believed to mean 'full of goodness.' It is associated with Saint Declan, a 5th-century missionary who founded a monastery in Ardmore, County Waterford, predating Saint Patrick's arrival in Ireland. The name has gained modern popularity outside Ireland, particularly in the United States and the United Kingdom, reflecting a broader trend of embracing Celtic names.
