Carol McCormick

Mrs. McCormick is Kenny, Kevin, and Karen's mother as well as Stuart's wife. Her first name is uncertain, however, she is often referred to as "Carol", a name that was used for Sharon Marsh, Sheila Broflovski, and Linda Stotch in earlier seasons.

Religion
Her family seems to be fairly religious and Roman Catholic, like most of the townspeople. She yells at Kenny for wanting to miss church in South Park: Bigger, Longer & Uncut for "Terrance and Phillip: Asses of Fire" while Stuart stood up for the Church in "Red Hot Catholic Love", where they were one of the few families in town that didn't convert to atheism. They also continue to pray after Kenny has died on a few occasions, and Kenny's funerals, when they occur, are always religious in nature.

In "Coon vs. Coon & Friends" it is revealed that she joined The Cult of Cthulhu for free beer and regrets it because she has to rebirth Kenny every time he dies.

Interests
She seems to like knitting. In "Cartman Joins NAMBLA", she is seen knitting when Kenny tells her that he made her favorite drink. She also says that making a sweater is better than molesting children in "The Wacky Molestation Adventure".

Voice acting
From 1997 to 1999, she was voiced by Mary Kay Bergman. Bergman described the character as one of her five favorite voice roles in the series, together with Liane Cartman, Sheila Broflovski, Wendy Testaburger, and Shelly Marsh, also mentioning that she based the voice of the character on a "female version of Bill Clinton". After Bergman's death, the character was voiced by Eliza Schneider, from 1999 to 2003. Since 2004, her voice has been provided by April Stewart.

Appearance
Mrs. McCormick wears a lime-green T-shirt which usually reads "I'm with Stupid", and dark blue jeans. The arrow is supposed to point at Stuart, but she is usually standing on the wrong side of him, so it points off in some other direction. Her hair is red, and similar in style to that of little Red's, but her bangs go in the same direction as Wendy Testaburger's. She has a shadowy patch on her right cheek, which may be a bruise, or simply filth.

In "Cartman Joins NAMBLA", her shirt had an American flag embroidered on it, accompanied by the phrase "God Bless". When the McCormick's went on the John Denver experience, however, it appeared as a solid green T-shirt. In "Best Friends Forever", it is a solid, but darker green.

For special occasions, she wears a fake fur coat with a red bathing suit top underneath and a red miniskirt, although in recent seasons she seems to have a much more black fancy shirt and dress with a veil.

At night she wears a nightshirt with several bunnies on it and pajama pants.

As of "The Ring", like many other adults, her appearance has been cleaned up, including small subtle changes to her hairstyle, T-shirt, arms and pants.

Personality
Like her husband, Stuart, she is drunk more often than not, though she does seem a lot more controlled with her drinking. She and Stuart are usually fighting and bickering, with Mrs. McCormick saying that if Stuart would stop drinking and being lazy, and get a job, they might not be so hungry and poor. Like Stuart does to her, she sometimes beats him physically, once giving him a black eye. She seems to have strength, seeing as when she hits Stuart. She also tackled Gerald Broflovski to the ground in I'm a Little Bit Country.

Mrs. McCormick does care for Stuart deep down, though, as she was concerned for him when he went ill after consuming a drink mixed with abortion medication, got his nose broken on the John Denver experience, and was molested by the entire NAMBLA Society in "Cartman Joins NAMBLA". However, she also seems to think that the McCormick residence primarily belongs to her, as in "Chickenlover", she says (regarding Stuart): "I want him out of my house! He ain't worth a shit! He can't even hold a fuckin' job!" and yells a similar phrase at him in "Best Friends Forever". However, Stuart and Gerald built that same house when they were teenagers, as revealed in "Chickenpox".

In the episode "Mysterion Rises" it is revealed she had been part of a cult centered around Cthulhu ten years before the series' events and that she had been with Stuart at the time. Although she and her husband claim to have been extremely drunk while there, something their son does not question, it is hinted their involvement may have been greater. It is also revealed Kenny under the guise of Mysterion has been manipulating them to make them act better, promising him not to get high at night, not to fight as much, and to pay their children an allowance.

Father
It is unclear if Kenny's grandfather, seen in "Fat Camp", is her father or Stuart's, as his name was not given. However, Gerald mentions in "Chickenpox" that Stuart's father was an unemployed drunkard like Stuart; what can be taken from this is ambiguous.

Mother
In "Best Friends Forever", it is mentioned that Kenny has a deceased grandmother.

Stuart McCormick
Stuart is her husband. With Mrs. McCormick being twenty-five years old, and Stuart being around Gerald Broflovski's age, there is approximately eight years between them. Little is known of their past, but they have been together for at least ten years, likely as old as their elder son, and share a love of drinking and drugs. Although they fight extremely often and have severely beat each other, it seems to be reinforced that they do care about each other, particularly in "Cartman Joins NAMBLA".

Kevin McCormick
Kevin is her elder son and child. He has not had many speaking roles, but when he does talk, he often repeats himself, implying that he is not very intellectual. Little is known of his relationship with his mother, although she seems to care about him as she scolded Kenny for not sharing a blanket with Kevin in "Spookyfish".

Kenneth "Kenny" McCormick
Kenny is her second child and younger son. She does care deeply about her son, crying and being horrified at many of his deaths, and arranging funerals, despite an implied knowledge of the repetition of them. She tries to make extra allowances for him during her pregnancy so he does not feel left out or ignored. She is, however, somewhat confrontational with him at times, such as South Park: Bigger, Longer & Uncut.

She is afraid of his alter-ego in "Mysterion", whom he uses to scare his parents into submission and manipulate them. When her children are taken away she does not want to see them go.

In "I Should Have Never Gone Ziplining", she and her husband were shocked and extremely disturbed when Kenny's remains were delivered to them by Mr. Hankey, which further reinforces her love for him.

Karen McCormick
Mrs. McCormick's youngest child and only daughter. Karen is a rather shy and timid child, often relying on Kenny for support and protection, although she and her mother may have a good relationship as seen in "The Poor Kid", when Mrs. McCormick holds Karen in her arms while trying to stop a fight between Stuart and Kevin and when Karen and her siblings are in "The Soft Room" she asks for her mother.

Trivia

 * At the end of "Cartman Joins NAMBLA", after Kenny dies, she gives birth to a baby who looks just like Kenny. She mentions this being the fifty-second occurrence of this happening. This indicates that every time Kenny dies, he is reborn and grows to be his age within a day's time. This is later reaffirmed in "Coon vs. Coon & Friends", when at the end Kenny kills himself.
 * Mrs. McCormick has a good memory as revealed in "Cartman Joins NAMBLA", when she recounts that she had gotten pregnant fifty - two times, with each previous child dying.
