As Irish surnames transitioned into given names, Tierney gained popularity in English-speaking countries, particularly in the United States and Ireland. Its usage as a first name reflects broader trends of embracing Celtic heritage and unisex naming. While not tied to any single religion, it is common in Christian-majority cultures due to Ireland’s historical context, but it is inherently multi-faith in application.
