Dark-haired or little dark one
Kierrah is a modern American spelling variant of the Irish name Ciara. It is derived from the Gaelic word 'ciar', which translates to 'dark' or 'black', originally used to describe someone with dark hair or a dark complexion. This specific spelling adds a contemporary flair with the 'K' and the 'h' ending.
