From Dale E. Pasco of Owosso: "My parents were both one room school teachers and they taught it this way: I'm a Michigander, my wife is a Michigoose, our kids are Michigoslins, so what is the use."

Gander is male goose. If you use “Michigander,” you should also include “Michigoose” (female) and “Michigosling” (child) in your title.
