I don't know if I can help you but I just wanted to tell you that my mother's maden name is Kauanoe. Dorothy Kahikilani (Kauanoe) Mahoney . She is from Oahu. Her father's name is Harrington Kauanoe, and his mother and father were Annie Kauanoe, and Mahana Kauanoe.
They are both from Oahu. If you have any information on any of this please let me know.
