question: Where did Ndvungunye's father die?
context: Title: Ngwane III
  Passage: Ngwane III was King of Swaziland from 1745 to 1780. He is considered to be the first King of modern Swaziland. For his name the people were called bakaNgwane and the country was called kaNgwane or "lakaNgwane". Ngwane was the son of Dlamini III and Queen LaYaka Ndwandwe. Dlamini was succeeded by Ngwane III his son with Queen LaYaka Ndwandwe. He took over the Dlamini chieftaincy
  and established settlements south of the Pongola River, later moving them to the north of the river banks. This makes Ngwane and his followers the founders of modern Swaziland. Ngwane ruled his Kingdom from the south east of Swaziland in the present Shiselweni district and his headquarters were called Zombodze at the foot of the Mhlosheni hills. It was at Zombodze that the Nguni ceremony "incwala" was celebrated for the first time.
  Title: Ndvungunye
  Passage: Ndvungunye (also known as Zikodze, Mavuso II) was King of Swaziland from 1780 until his death in 1815 after succeeding his father, King Ngwane III following a very brief regency of Indlovukati LaYaka Ndwandwe. Very little has been recorded of the quality of leadership under his reign. Ndvungunye built his residence or "Sigodlo" near Mhlosheni on feet of the eMhlosheni hills in NShiselweni, the south east of modern Swaziland near Zombodze, where his father Ngwane had settled during his reign. His rule thus indicated a period of limited expansion and consolidation which is overshadowed by that of his son King Sobhuza I. The NShiselweni settlements established under his reign which he placed under the guardianship of his chief Sukumbili Mbokane would not however provide a solid foundation for the future Swazi state as indicated by attacks after his death on Sobhuza by Ndwandwe chiefs. Ndvungunye died around 1815 after being struck by lightning. Ndvungunye was married to Lojiba Simelane and Somnjalose Simelane. It was with the latter that he had his son Sobhuza I. Lojiba however became Queen mother as she was a senior sister to Somnjalose. Sobhuza I became the king in 1815 after the regency of Queen Lomvula Mndzebele.
