The House of Ke?ua Nui(Hale O Ke?ua Nui) or the simply Ke?ua rather than Ke?ua Nui (Ke?ua the Great), was a non-ruling noble family of the Big Island from which the reigning family of Kamehameha I and Kalaimamahu branched from. Today, the only surviving line of Keoua's children is the royal line of his first son, Prince Kalokuokamaile. [1]
Ke?ua's paternal lineage derives from a branch of the Hawaii alii aimoku family. His father, the High Chief Keeaumoku-nui of Kohala and Kona, was the second son of Keaweikekahialiiokamoku, King of Hawaii Island and his half-sister bride, Kalanikauleleiaiwi. He was a pio chief and of the highest rank. Even outranking his elder brother Kalaninuiamamao, from which descends the Houses of Kalakaua and Kawananakoa. It was because of these two brother, who contested for the succession to the kingship of the island of Hawaii after Keaweikekahialiiokamoku death, that the island was dissolved into a handful independent warring fractions.
The ancestry of Kalokuokamaile?s mother, the High Chiefess Kamaka'imoku, daughter of Alii Ku'a Nu'uanu, Oahu district chief descended from the Alii of Hilo who were the descendant of King Umi's youngest son Kumalae, first Alii of Hilo. His mother was also mother of Kalaniopuu, by Kalaninuiamamao, making him half-brother of Kalaniopuu and uncle of Kiwalao. Kamaka'imoku was also the half-sister of Heulu (through their mother Umiula-a-kaahumanu), the father of Keawe-a-Heulu, another ancestor of House of Kalakaua.
In 1795, Kamehameha, member of the House of Keoua Nui, conquered the separate islands uniting them under a single monarchy. He established his own royal house, the House of Kamehameha. His siblings' houses were considered a part of the royal family.
