Dear Kezhia,
I had a lovely time looking up your name, and I think I found something for you...
The name is from India, and it actually has a double derivation. In Hebrew it means most beautiful woman, kind-hearted and hospitable. However the name also derives from Lord Krishna, who was known as Keshava.
Here is a link for you, in case you want to read more, plus a video someone posted on YouTube of their beautiful tiny daughter to whom they have given the name of Kezhia Faith.
