Princess Ka'iulani's full name at birth was "Victoria Ka'iulani Kalaninuiahilapalapa Kawekiu i Lunalilo Cleghorn," first born child of a Hawaiian Royal mother and a Scottish commoner father. She was born October 16, 1875 in the city of Honolulu, island of Oahu, Kingdom of Hawaii.
Her given first name, Victoria, was a tribute to the then reigning Queen regnant of Great Britain. In July 1843, Queen Victoria had helped to restore the sovereignty and independence of the Kingdom of Hawaii during the reign of King Kamehameha III. Just like Queen Victoria, whose given names were Alexandrina Victoria, but who chose not to use her given first name and to be called simply Victoria, Princess Ka'iulani chose not to use her given first name of Victoria, and to be called simply Ka'iulani.
