In our family, calling an aunt "Auntie" was (and is) a mark of respect and affection. My sisters and I had a few aunts, but only one Auntie, our favorite (my mom's twin). No other name was needed--she was just Auntie. Now, as an adult, I'm delighted to be one of the Aunties of my generation.
It's the same with "Cousin" or "Cuz," which in our family are affectionate terms rather than being formal honorifics. I enjoy calling one of my cousins and saying, "Hi Cousin, it's Cousin Marian" or just "Hi, Cuz." And if you get called "Sweet Cuz," you're really the top!
I'm certainly going to note these honorifics in the family story. What are your family's honorifics?
