My Mama is from southwest VA. All of her sisters have three names. None of them use their first names except when they are ticked at each other.
I have an Aunt Ducky, Aunty Sissy (no part of her name is Sissy), Uncle I-Do, Uncle Junior (he isn't a Junior). Another Aunt dates a man I have only herd referred to as "Melon". I have a cousin called nothing but "J. Possum". His name is Doug. Beats me how that happened.
