Some of E's do!
Uncle Ben : U-B, like it sounds, you-bee. Well, it's what he wants E to call him, anyway. The other nephews call him Uncle Benny).
Aunt Debra : A-D (like Haiti, without the H)
Aunt Lisa: Auntie Lee-Lee)
Aunt Emily: Auntie Em
Uncle Jesse : well, not him, that's his name, but Uncle Jesse!
I have more siblings, but they'll just be called by their names.
My dad is Jonathan and is called Uncle Donny by my cousins due to my uncle not being able to pronounce Johnny as a child. My aunts and uncle still call him that.
My aunt Melissa Ann is San.
My aunt Julianna is Gilly. I don't know why.
(I wasn't sure if this should go under Names or Family, so please feel free to move!)
