There isn't, but there is a character in Chicken Run called
Edwina. This is the only pop culture (animated or otherwise)
Edwina I can think of.
She was the chicken who was taken to the cop at the beginning.
My personal thoughts on the name is that it has a comedic sound to it, like
Ethel and
Betty. The comedic sound can stem from the fat that it's a pretty dated name, but also maybe the weird "ween" sound. Words that "sound comedic" are often always the ones that makes your mouth form a smile when saying it, so the comedy is rather inherent with the name.
