- "I'm sorry to bother you like this, but my son, Matthew, he's got a slight fever. I'm sure it's nothing but I don't want to take any chances."
- —Marianne to Stevens.[src]
Almost nothing is known about Marianne's life before or as the outbreak began. It is known that she has a son named Matthew. She may have lived in or near Woodbury before or during the outbreak.
Marianne Dolan once stopped traffic with her olive-skinned French-Canadian beauty, her hourglass figure, and enormous blue-green eyes. A decade and a half of hard housework and single parenting took its toll on her looks, and the plague times deepened the lines around her mouth and eyes.
Ms. Williams appears when her son has a fever. She goes to Stevens and supposedly schedules an appointment with him. The next day, she tells Austin about her encounter with Stevens, and later her son is treated by Bob.
After The Governor is killed and the six surviving members of his army return after attacking the prison, Marianne hears the news about their former leader's true nature. After Lilly Caul takes the position of leadership in Woodbury, Marianne is one of the twenty-nine remaining survivors, being among the seven remaining women.
Assumed that Marianne stayed in Woodbury, she was possibly killed by the walkers that overran Woodbury when the Pentecostal People of God blew the gates to Woodbury. If she did not escape - as it shown only a few Woodburians survived the attack, escaping onto the court house roof - she is most likely deceased.
This list shows the victims Marianne has killed:
- Possibly numerous counts of zombies.
Matthew Williams is the son of Marianne, and although they are never seen together, it is presumed that they had a basic mother-son relationship.Marianne obviously cared about Matthew due to Marianne seeing Stevens about Matthew's fever.
We can assume that the were acquainted with each other. Marianne is the last Woodbury citizen to speak to Dr. Stevens when she tried to make an appointment with him for her son, Matthew Williams because he was running a fever.
- The novel series state that Marianne's last name is Dolan, however, comics state it's Williams. This is most likely an error or it could be her maiden name.
