Buhera is an adulterated Ndebele name?

Adopted from the book titled #v=onepage&q=buhera%2Bbuyela&f=false">The Blind Child: Experiences Public Life (Based on a true story) by Rudo Moyo.

It is widely believed that the Manyika people in Buhera originated from Swaziland and on being asked when they would go back to their country, they kept on saying 'Siyabuyela' and Buyela meaning go back was then distorted to Buhera.
