Tierney

Tierney is a Celtic surname with a definite Irish twinkle, a name just waiting to be discovered. Though now sometimes used for girls (in the US, not Ireland), as in jazz singer Tierney Sutton, it still has plenty of masculine punch.

Tierney, in its original Tiarnach form, was the name of several saints. It can also join the ranks of Old Hollywood names, via the haunting actress Gene Tierney. ER actress Maura Tierney is a current surname bearer. 

As of October 2026, Tierney ranked #9490 in US births in 2006 SSA, peaked at #6422 in 1976.
