Slight correction.  KS does allow non-aboriginal Hawai'ian children.  That's why the IRS lost in court, 3 times.  I had one in my class but nobody really made a fuss about it because it was school.  In actuality, my younger brother was only able to get 3 out of his 5 kids into KS.  I told him, "Easy...just get divorced and it'll be easier."  I wasn't joking because "...and to devote a portion of each years income to the support and education of orphans, and others in indigent circumstances, giving the preference to Hawaiians of pure or part aboriginal blood;..." was later interpreted by the Trustees (can't remember when or whom) to include "and others" to mean kids from broken homes.  When the federal govt kept trying to force rules upon the estate, sadly the JROTC program was abolished so that no federal monies would allow govt meddling in the affairs of the schools.
As for the name change, the closest easiest explanation would be how Trusts, any Trust, can form LLCs to do business.
