Marjorie "Marge" Bovier Simpson is voiced by Julie Kavner and is Homer's beautiful wife on The Simpsons.  Marge is the loving mother of Bart, Lisa and Maggie and is a stay at home mom.  Thank goodness cause Homer isn't doing much to raise the family or keep the household in order.

Marge's sisters, Patty and Selma are frequent characters on the show and we've even met her parents, Clancy and Jaqueline Bouvier a couple times.
