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.

Fierce meaning, gentle image. This name is very common in Israel, where an endearing pet form is Dubi.

Like Harbor, one of the new generation of word names with appealing meanings, though (female) memoirist Haven Kimmel has tipped it decidedly toward the girls' side.
