I found a scholar who has done a ton of work on Mainland Hawaiian culture! Her name is Rona Tamiko Halualani and she teaches at SJSU in the department of communication studies. She wrote a book on Mainland Hawaiian culture even, In the Name of Hawaiians, which I definitely need to get my hands on, not just for my literature review, but for my entire thesis.
This discovery changes so much and I am so excited. I am a little ashamed to say though, that I found her through a google scholar search when all of my other searches and resources came up empty handed. Also whatʻs exciting, is she was in a PBS special, called American Aloha and Aunty Sissyʻs Halau, Halau o Lilinoe was featured. Once i get ahold of the book, or the professor (although iʻd ike to read her book first and sound like an informed student), iʻll post more.
