Ndzhukula/ Nzukula is the Tsonga version
Zucula is the Portuguese version
Zukula is the original

Centuries ago, an old man named Nzama used to reside at a place today called Swaziland before Mswazi himself and Sobuza were born, before africa was divided in 1883 to 1886. History taught us that Nzama was a lala, he spoke the language. The old man had for sons namely Khungeka, Hlaba, Zukula and Khuba.

Remember that surnames give birth to one another and last time i checked the Xitlhangu kumbe sihlangu do not a name Ndzhukula in their clan praise. And the Tsongas do not provide a clear interpretation of this whole thing. Zukula was swallowed and assimilated by the Tsonga people.

If the place the Ndzhukulas are living at is eBalaleni and and Nzama who was Zukulas father was a Nzama it means they settled long before so much. Because yes indeed, history teaches us that the migration took place paved by the ongoing civil wars and looking for green pastures.
