In the comic it's Willhelmina. In the TV show it's Willma :]

I always thought it was both, like her mom didn't want always say Willhelmina, so she said Wilma. Which Will hated both and went by Will

okey :) thank u... I am only reading the comic, so I dont know so much about the TVshow.

no prob...

I agree with MondayTonality. In the comic it's Willhelmina and in the TV show it's Willma. I like her name: Willhelmina, because we can call her Will or Mina.
