High Chief Peleioholani La'anui was the son of High Chiefess Ka'ohelelani & Chief Nuhi O Hinai, born at Waimea, Hawaii. La'anui was the famous chief that survived the slaughter at the battle of Kawaihae.
A royal alliance was made by King Kamehameha and Queen Kaahumanu by arranging the marriage between Namahana Kekuwai-Pi'ia (the Queens sister) and La'anui and for them to move to Waialua, Oahu to govern that district. They were the first couples to be baptized in Kawaiaha'o Church along with Queen Ka'ahumanu and seven other followers where he received his baptismal name of Gideon.
Kekuawai-Pi'ia later died with no children from La'anui.
La'anui was then introduced to the Queens twin adopted daughter of Holau and married the High Chiefess Theresa Owana Kaheiheimalie Rives, daughter of Luahine. Their off springs brought them a daughter, Elizabeth Keka'aniau and a son, Gideon Ka'ilipalaki La'anui II. Several months after their son, Ka'ilipalaki La'anui was born, Theresa Owana Kaheiheimalie passed away from illness. Peleioholani La'anui then married Puohu, but had no children from her.

His daughter, the High Chiefess Elizabeth Keka'aniau was selected by King Kamehameha III to be eligible to the throne of the Hawaiian Kingdom and was groomed to be a future ruler of Hawaii, entering the Chiefs' Children's School.
Gideon La'anui was the most skilled surf rider, taught by King Kamehameha himself at Haleumiumiiole at Kawaihae and at Kapuni, outside of Kiikiiakoi. Later, La'anui passed Kamehameha's teachings of surfing on to the young sons of Kamehameha at a place of what is now known as Ali'i Beach in Hale'iwa. When Kamehameha died, so great was La'anui's love that he knocked out his teeth in respect for his great uncle.
La'anui's old estate, land he gave to Reverend Emerson to build the Waialua Protestant Church, now called the Lili'uokalani Church
La'anui was the High Chief of Waialua on O'ahu were he resided and was the judge of his district appointed by King Kamehameha III. He initiated the first congregation in Waialua and donated all the land for the church. It is now known as the Lili'uokalani Church. La'anui also donated a large portion of money for the original 400 pound bronze bell that still rings today, replacing the blowing of the conch shell call to worship.
The ancient royal Loko'ea fishpond as well as 'Uko'a pond was owned by La'anui where Kamehameha himself used to pull fish from. The ponds dates back to the year 1600, now transferred to the possession of the Kamehameha landholding trust of Princess Bernice Pauahi Bishop after the death of La'anui.
