I'm from Alabama & have an Uncle Bo (Paul), & another Uncle called my Brother Patrick Allewishish (don't know how to spell such a name) for Patrick. Aunt Gin is for Virginia, Ruby is Boo & Uncle Marvin is Tiny or Uncle Tiny. My Mom called me Sister Bill, but no one else that I recall did. I asked her why that & she didn't have an answer. My Son asked what I wanted to be called when my DGD was borned. I told him nothing with Grandmother/Grandma, etc, so Mama Sheila was OK. I'm Mama Sheila still to lots of folks or Aunt Sheila. I also have a Neice Bethany whose Nickname is Kricket because she is frightened to death of Krickets. My Son had a big banner made for her windshield says Kricket. She is now a high school teacher, but I don't know if the students know her by Kricket. I'll have to ask. Great post.
