History tells me that, when Soshangane came to settle in Ndau area running away from Zulu battles(under Shaka), he found Ndau people. Soshangane(also known as Manukosi,the grand father of Ngungunyana) and his people(Known as Gaza Nguni) reached the central Mozambique and earsten Zimbabwe which already inhabited by Ndau people in 1820's. For decades, the Ndau people were prejudiced by the Nguni speaking people(especially Ngungunyana). I am atold that Soshangane ruled over a military state with age regiments for male warriors based on the Zulu model in South Africa.
However, centuries earlier, Shona speaking(Karanga) chieftancies) had dominated some of the same TSONGA speaking groups that came to live under Soshangane(mind you, the Ndau people were always there, as Ndaus with their Ndau Chieftancies). At the beginning of the 19th century, the Tsonga chieftancies, had asserted their autonomy to establish themselves as culrurally distict from Ngunis and Ndaus.They then called themselves Shangani(after Soshangane) the first Gaza Nguni leader, who settled in their midst.
I would agree if you say, during the interaction and cross OR INTER marriages amongst Ndaus, Gaza ngunis, and Shanganis, SURNAMES AND TOTEMS WERE ALSO shared. thus, you may find Sitholes amongst all these groups. But thanks for your input, my search si still on, Hope to get more input on this subject.
Pleasee can you give me, the Sithole salutation, for example, Sithole Moyo or Chirandu or Mapfudze or Ntini. I am not sure. if you know this. Please help me.
