||Carter Pewterschmidt, voiced by Seth MacFarlane
Status: Married to Barbara Pewterschmidt
Carter is the father of Lois, Carol and as we learn in “Fat Guy Strangler”, (& then unknown to Lois and Carol), a son named Patrick.
It it seen in an unfinished animatic on one of the DVD sets, Carter and Barbara have another daughter who is a twin to Lois that is kept in a cage in the basement, however she has never been mentioned in the series proper.
Lois also suggests in “Screwed the Pooch” that Carter has fathered a bi-racial child unknown to Barbara.
He is a millionaire who is friends with the likes of Michael Eisner, Ted Turner & Bill Gates.
He was first introduced in the episode “Peter, Peter, Caviar Eater” and we learn he hates Peter and would do anything to get rid of him, including once offering Peter a million dollars to leave Lois.
In “Peter Griffin: Husband, Father...Brother?”, we learn that Carter's ancestors once owned Peter's ancestor Nate Griffin and paid Peter $12,000 in reparations.
Carter does not believe in gay marriage or legalizing pot, mainly because legalizing pot cuts into his profits in the timber industry.
In the episode “Peterotica”, Carter gives Peter 5 dollars so he can publish his series of erotic novels.
Due to a traffic accident involving a reader, Carter is sued and losses all his money.
Barbara leaves him and marries Ted Turner only to soon divorce him and returning to Carter taking half of Ted's fortune with her.
To show how much contempt he has for Peter, Carter has made him eat a pine cone, drink his blood, pushed him into a fire & retrieve a $5 bill at the bottom of a jar filled with salt and barbed wire however in the episode, “Padre De Familia”, Carter finds a small soft spot in his heart to hire Peter to work at his estate when Peter can't find work anywhere else.
In the episode “Ocean's Three and a Half”, Peter, Cleveland, Glen & Joe attempt to steal Carter's money to help pay Joe's medical bills. Joe eventually stops them and Lois asks Carter to load her the money. When Peter asks how she got the money from her father, she tells him it was to hire a divorce attorney.
In “Peter's Progress”, we discover that apparently in a past life Carter was a man named Lord Redbush who was the father of Lady Redbush who happened to look a lot like his daughter Lois.
Carter has made appearances in the episodes, “Peter, Peter, Caviar Eater”, “Death Lives”, “Screwed the Pooch”, “Peter Griffin: Husband, Father...Brother?”, “Family Guy Viewer Mail”, “Model Misbehavior”, “The Fat Guy Strangler”, “Peterotica”, “Bill and Peter's Bogus Journey”, “Blue Harvest” (as Uncle Owen), “Believe it or Not, Joe's Walking on Air”, “Padre De Familia”, “Ocean's Three and a Half”, “420”, “Three Kings” (as Warden Norton) & “Peter's Progress” (as Lord Redbush)
