Ncube Clan Origin:
Mncube/Ncube on the following surnames:
Ncube, Mncube:* Khambule, Mlotshwa, Mzilankatha, Ngcamu, Mpangazitha, Zikhali, Makalima
All these surnames are actually Mncube/Ncube surnames but people opted to use toetems and grandparents names as surnames. I think you should look at the origins of the surname Ncube before assuming that it is a Kalanga surname. In actual fact these people are Sotho descendants and not Nguni. Research on the above surnames and you will discover that its actually one and the same surname with one toetem for all of them.
I do not dispute the fact that The Ncube surname has been used by the Kalanga and shona tribes (Malaba, Shoko etc), but these Ncubes are totally different from the Mzilankathas and are not Sotho descendants.
See below the history and origins of the above mentioned surnames and how they relate:
