Haʻaheo Kaniu

Haʻaheo Kaniu or Kaniuʻopiohaʻaheo (late 18th century – ) was a high chiefess (aliʻi) and member of the royal family of the Hawaiian Kingdom. She was also known as Lydia Haʻaheo Kaniu.

Genealogy and family Haʻaheo Kaniu was born in the late 18th-century. Sources on Haʻaheo Kaniu's genealogy are conflicting. An 1858 court case named Kalailua as the mother of Haʻaheo Kaniu and stated Kalailua was sister of ʻAikanaka (maternal grandfather of her future hānai son Kalākaua).

Historian Abraham Fornander named High Chiefess ʻAkahi as her mother, who was a sister of Keawemauhili, Aliʻi Nui of Hilo and a rival of King Kamehameha I who conquered the Hawaiian Islands into a unified kingdom by 1810. This ʻAkahi was the foster mother of Keawemauhili's orphan daughter Kapiʻolani who became a later famous convert to Christianity. According to historian Sammy Amalu, she was the daughter of ʻAkahi-a-Kawalu (different from Fornander's ʻAkahi) and Keōua Kalanikupuapaʻīkalaninui Ahilapalapa, the father of Kamehameha I.

Haʻaheo Kaniu married to Kaikoʻokalani, the son of Kamehameha I and Peleuli. She also married Kuakini, who adopted the name John Adams and served as Governor of Hawaii Island. Kuakini was the younger brother of Kamehameha I's favorite wife Kaʻahumanu who served as Kuhina Nui (regent) for King Kamehameha II. With Kuakini, Haʻaheo Kaniu was the mother of Kamānele who was betrothed to Kamehameha III before her death at a young age. Both later remarried. Her final marriage was to Keaweamahi Kinimaka, a chief of lesser rank.

Conversion to Christianity American Protestant Christian missionaries arrived in Hawaii from New England in 1820. Three years later, around 1823, Haʻaheo Kaniu and her husband Kaiko became two of the earliest converts and accepted the new faith along with Queen Keōpūolani (the first royal to convert), Hoapili, Princess Nāhiʻenaʻena, Keʻeaumoku II, Kekauʻōnohi, Wahinepio, and Kaukuna Kahekili. These chiefs all attended classes set up by the American missionaries Charles Samuel Stewart and William Richards on the island of Maui. After her conversion to Christianity, she adopted the English name Lydia Haʻaheo Kaniu.

According to the testimony of Nauhele (a member of her family), Haʻaheo Kaniu died in 1843, in Honolulu. In a verbal will witnessed by Oahu Governor Kekūanaōʻa, she bequeathed all her properties in Honolulu and Lahaina and on the islands of Hawaii and Molokai to her hānai son with her widower Kinimaka holding onto the properties until Kalākaua came of age. After her death, Kinimaka was given guardianship over Kalākaua. Kinimaka would later marry Pai, a subordinate Tahitian chiefess, who treated Kalākaua as her own until the birth of her own son. Eventually, Kalākaua returned to live with his birth parents. Kinimaka named his daughter Haʻaheo Kaniu Kinimaka after her. Kinimaka died in 1857. In 1858, Kalākaua successfully sued the heirs of Kinimaka for the rights to Haʻaheo Kaniu's landholding in a case presided by Supreme Court justice George Morison Robertson.
