Thanks for the heritage lines.
Auntie Toot (sounds like Annie) IS an HI term. Was there just a week and had several people call me that. I asked a native the significance of the name and was told it was a term of endearment given to marriage woman, elder or wise elder. He was the one who informed me it was Auntie not Annie even though it sounded like the later.
That’s odd. I lived in HI for 14 years and never heard anyone called that. I heard “Tutu” used exclusively for grandparent, usually grandmother; “Auntie” is used frequently for an older female relative or family friend. Also, the Hawaiian accent accentuates the “t” sound in “Auntie” quite strongly, don’t see how it could possibly sound like “Annie”. I never heard “Autie” and “tutu” used together, and never heard “Toot” used instead of “tutu”.
Technically, “tutu wahine” means grandmother, and “tutu kane” grandfather, but generally “tutu” is used for grandmother. Maybe among Hawaiian speakers they use tutu wahine and tutu kane, but among the general public I didn’t hear it.
