He never officially converted to Christianity because he refused to give up four of his five wives and his love of alcohol. He (like his father) married several relatives of high rank, but he was the last Hawaiian king to practice polygamy. His favorite wife was his half-sister Kamāmalu. Kīnaʻu (Kamāmalu's full-blood sister) was his second wife who would later remarry and become Kuhina Nui. Princess Kalani Pauahi was his niece by his half-brother Pauli Kaōleiokū. She later remarried and gave birth to Princess Ruth Keʻelikōlani. Kekāuluohi was half-sister of Kamāmalu and Kīnaʻu through their mother Kaheiheimālie who was another of his father's wives. Princess Kekauʻōnohi was Liholiho's niece and granddaughter of Kamehameha I, and would later become royal governor of the islands of Maui and Kauaʻi.
