The members of this clan all hail from the village of Tubou on the island of Lakeba and from their original roots in Nayau.
These four noble households are Matailakeba, Vatuwaqa, Koroicumu and Naivi and all claim descent from the first High Chief of the dynasty, Niumataiwalu, a grandson of Kalouyalewa.
The Tui Nayau, or Paramount Chief of the Lau Islands, has traditionally come from the noble house of Matailakeba.
Codro, who had Bauan roots and who now lived in Levuka (a village not far from Tubou), continued to torment and subdue the people of Lakeba.
Niumataiwalu, realizing that there was only one close relative alive, Delailoa (since all his brothers and his father were slain by Qoma's children that Niumataiwalu had exacted revenge for), and prior to his slaying in Ono, called Delailoa and sent him to Nayau to retain his name and their position of Tui Nayau.
They came down following the stream causing the women to say " sa vuvu mai na wai" meaning "the colour of the water has changed" thinking that it could be raining up in the mountains or people coming back from their farms as they didn't realise that Matawalu and his army had arrived.
It is said that when Matawalu swung his 'Wau' (War Club) to kill him it cut through the banana tree and decapitated the guard.
So when a particular person knows that his day is coming closer he will jump out and start swimming ashore where Matawalu's army were waiting.
