History & Origin
Kierah is a modern -ah spelling of Kiera, the feminine of the Irish name Kieran, from ciar, 'dark', with the affectionate sense 'little dark one'. Kira, a like-sounding name of Russian and other roots, blends into its usage. Parents took up this spelling in the 1990s; the Irish meaning is the best-grounded route.
It was never common, given to only a couple dozen girls a year in the mid-2000s. A girl named Kierah then is in her late teens or twenties now, from the peak of Kiera and Kira names.
