Keʻelikōlani, Hawaiian royal and governor (died 1883)

Ruth Ke‘elikōlani, or sometimes written as Luka Ke‘elikōlani, also known as Ruth Ke‘elikōlani Keanolani Kanāhoahoa or Ruth Keanolani Kanāhoahoa Ke‘elikōlani, was a member of the House of Kamehameha who served as Governor of the Island of Hawaiʻi and for a period, was the largest and wealthiest landowner in the Hawaiian Islands. Keʻelikōlani's genealogy is controversial. Her mother's identity is not disputed, while her grandfather Pauli Kaōleiokū's relationship to Kamehameha I is. While her father was legally identified as early as 1864, disputes to that lineage continued as late as 1919. As one of the primary heirs to the Kamehameha family, Ruth held much of the land that would become the Bernice Pauahi Bishop Estate, funding the Kamehameha Schools.
