EssexRoyal, It depends on which protocol you wish to follow. According to European standards it is clear cut and allowed being that the descent is through a Queen Regnant. In Hawai'i, according to Hawaiian protocol, the Prince is equal in status as his cousin HRH Prince Quentin Kawanankoa and if there were some sort of restoration to the Monarchy, The Prince Darrick would be in the line of succession according to hawaiian custom and therefore, the Council of Chiefs would appoint the next leader. It would then become a new stirps. Therefore any descendent with the genealogy to prove they are Ali'i Nui would be in the line of succession and would be eligible to he chosen. Quentin having put forth a full claim about 5 years ago is the recognized Heir to the throne in Europe but, in Hawai'i, he is considered one of many who could be chosen for the position. Since the Kamehameha line died out, the new Stirps became the House of Kalakaua and now, the Council of Chiefs would decide if it will become the House of Kawananakoa, Kamakahelei or whichever other head of a Royal House comes forward. It is as simple as that and it would be according to protocol. The Prince Darrick along with his cousin The Prince Kawananakoa claim their Houses through the Kings and Queens of Kauai', considered the bluest blood and the highest of rank in Hawai'i.
