Ok, I got to look at the links finally and ironically I noticed the 2nd link, the name in it I suspected was from Amelia Kuulei Gora. And when I re-read what you posted asking if these references are true, I suspected it was because of that one. For that one, and relation to Bernice Pauahi Bishop....please ignore it. Ignore anything that is written by Amelia and whatever you see posted either in her own blog or forums where she lays claims to vast estates due to her family if not specifically to her by way of Kalola, or by Isaac Davis, John Young and any other ali'i from back in those days. Her genealogy is inconsistent and in the past has hijacked others.
I can say this, since Kahalokahoupokapu was a chiefess, she's probably descended from many of the other chiefs just as many people today are, just that they don't know it.
