In Madeleine L’Engle’s A Wrinkle in Time, what is the name of Meg Murry’s youngest brother?

In Madeleine L’Engle’s A Wrinkle in Time, Meg Murry’s youngest brother is Charles Wallace.

Charles Wallace is the youngest of the Murry children and is unusually perceptive, speaking with an intelligence that surprises adults. At the beginning of the novel, many people in the Murry family’s small town misunderstand him because he does not behave like an ordinary child. Meg, however, recognizes how deeply he understands her.

Charles Wallace joins Meg and Calvin O’Keefe on the interplanetary journey to find their missing father, Dr. Alex Murry. The three children travel with Mrs. Whatsit, Mrs. Who, and Mrs. Which, using the concept of a tesseract to cross great distances.

Charles Wallace is sometimes confused with Calvin, who is Meg’s friend and classmate, or with the twins Sandy and Dennys. The Murry children’s family relationships are important because the story’s emotional conflict centers on love, individuality, and resistance to the controlling force called IT.
