He grew up as the favorite companion of Prince Kauikeaouli, who took the throne as King
Kamehameha III. The two friends' relationship was severely damaged when Keoni Ana was caught in the bedroom of Queen
Kalama, the King's wife, shortly after the birth of Prince
Keaweaweulaokalani in 1839. The sentence of death was only avoided through the intervention of Queen Dowager
Kalākua Kaheiheimālie. It seem after the incident, Kamehameha III forgave him. Keoni Ana held several government positions, including service in the
House of Nobles 1841–1856, the Privy Council 1845–1857, as a Supreme Court justice, royal governor of
Maui, and as chamberlain of Kamehameha III's household. He aided in communication between native Hawaiian and foreign elements in the community. He succeeded
Kekāuluohi as Kuhina Nui. After Keoni Ana became Kuhina Nui the Legislative Assembly passed several acts that organized the executive ministries and departments of the government. This legislation provided that the Kuhina Nui served also as Minister of the Interior. More far-reaching was the creation of the Board of Commissioners to Quiet Land Titles, which would forever change the system of land tenure in Hawaii in what would be known as the
Great Mahele. Keoni Ana served on a committee to assist the king and chiefs in defining their rights and interests in the lands within the kingdom. As a very close friend and ally of the Kauikeaouli, Keoni Ana recognized that the Kuhina Nui's authority challenged the king's prestige and power. Keoni Ana supported Kamehameha III and IV in their attempt to abolish the office. His position as Kuhina Nui was not renewed in 1855 by
Kamehameha IV, who chose his sister as the new Kuhina Nui, but he remained
Minister of the Interior. == Marriages ==
