Lois Griffin is Peter's wife on Family Guy and is voiced by Alex Borstein.

Lois was born to the wealthy Pewterschmidt family in Newport, Rhode Island.  Lois ended up marrying Peter, who was from a lower-income family, when she met him as a towel boy in her country club.  Yeah, none of us can figure out why she married him either.

Lois is a wonderful mother to Chris, Meg and Stewie, although Stewie is constantly trying to kill her and all.
