"Respelling"
The name Kieara is commonly a female name from the "English" origin.
Kieara first appears in United States birth records in 1987. It is a respelled form of an established name already in use in the United States at that time, either Kiara (the Italian and Spanish form of Chiara) or Kiera (an anglicized spelling of the Irish Ciara). The birth records alone do not show which of the two it was modelled on.
The pronunciation of Kieara is kee-AHR-uh.
