Barbara Pewterschmidt is the mother of Lois Griffin. She is married to Carter Pewterschmidt and the grandmother of Chris and Stewie. and Meg. In terms of behavior, she is the prime example of an American wealthy white woman: courteous, calm, naïve, and very loyal to the public. Nevertheless, she cheats Carter now and then, because neither he nor she can really suffer. Not worth reading haha.
