What does the name Kisha mean?

What does the name Kisha mean? In looking around, I found several sources on the name Kisha, but none seemed definitive. Kisha is definitively a girls name, as I found no references for any boys named Kisha or that it has been used for naming boys.

Here are a couple of samples for potential meaning:

The name Kisha, is of slavic origin and means “Rainfall”.

The name Kisha, is a name used in English, is of recent invention and is a derivitive of the name/spelling “Keisha” or “Keziah”. Keziah, supposedly means “cassia” in Hebrew, from the name of the spice tree. In the Old Testament of the bible, Keziah was a daughter of Job.

Another resource points to origins in India, with the meaning of the name being “A girl with beautiful hair” and comes originally from a Sanskrit word and is pronounced Kee-Shah.

Finally, another reference points to an African origin to the name Kisha, with the spelling also derived from the spelling “Keisha”, and the meaning being “favorite”.
