Combination name; possibly she is or born at Christmas
Tashona is a modern American invention, likely created by combining the prefix 'Ta-' with the name Shona. Shona itself can be a Gaelic form of Joan, meaning 'God is gracious', or a reference to the Shona people of Zimbabwe. In some contexts, it is used as a variation of Tasha, a diminutive of Natasha, which means 'birthday' in reference to Christ.
