The sibling relationship between Marilla Cuthbert and Matthew Cuthbert

Marilla Cuthbert and Matthew Cuthbert are brother and sister, the sole remaining occupants of Green Gables, a farmstead built by their father at the furthest edge of his cleared land, barely visible from the main road. They are both unmarried and childless, living together in a routine of quiet industry. Matthew is shy, silent, and avoids strangers; Marilla is angular, rigid in conscience, and keeps the house with a precision that makes the kitchen look like an unused parlor. Their household is self-contained, lacking any child until the day Matthew brings home Anne Shirley by mistake.

The Shape of Their Partnership

Marilla is the manager of the household and the decision-maker; Matthew is the farmer who works the land. When Matthew sets his mind on something, Marilla gives in, as she does when he insists on keeping Anne after the initial mistake. "It's so seldom Matthew sets his mind on anything that when he does I always feel it's my duty to give in," she tells Mrs. Rachel Lynde. Matthew, for his part, defers to Marilla's authority in raising Anne, promising not to interfere with her methods. Yet he quietly subverts her decisions when he believes Anne needs something Marilla will not provide—buying her a dress with puffed sleeves, slipping upstairs to persuade her to apologize to Mrs. Lynde. Marilla knows he does this and resents it, but she tolerates it. Their partnership is not one of equals in temperament, but of complementary roles that have worked for decades.

The Unspoken Bond Tested by Anne

Anne's arrival forces both siblings to confront feelings they have never had to articulate. Matthew, who dreaded little girls, finds himself enjoying Anne's chatter and defending her to Marilla. Marilla, who never wanted an orphan girl, gradually admits that the house seems different with Anne in it. When Anne first kisses Marilla's cheek, Marilla feels "a sudden sensation of startling sweetness" that she cannot name. When Anne breaks her ankle, Marilla realizes with a stab of fear that Anne is "dearer to her than anything else on earth." Matthew, watching Anne grow, tells Marilla that she has been "a blessing to us." Neither sibling ever says such things directly to each other, but their shared pride in Anne becomes a new, unspoken bond between them.

Grief and the Revelation of Love

Matthew's sudden death from heart failure, triggered by news of the Abbey Bank's failure, shatters the household. Marilla, who has never been demonstrative, breaks down and weeps bitterly. That night, when Anne cries in her room, Marilla comes to her and speaks with a vulnerability she has never shown: "I know I've been kind of strict and harsh with you maybe—but you mustn't think I didn't love you as well as Matthew did, for all that. I want to tell you now when I can. It's never been easy for me to say things out of my heart, but at times like this it's easier. I love you as dear as if you were my own flesh and blood and you've been my joy and comfort ever since you came to Green Gables." In this moment, Marilla reveals that her love for Anne is not separate from her love for Matthew—it is the continuation of the family they built together. The loss of Matthew makes her cling more fiercely to Anne, and when Anne decides to give up her scholarship to stay and teach, Marilla yields, calling her "you blessed girl." The sibling relationship, tested by grief, emerges transformed: Marilla, once rigid, becomes "mellow," as Mrs. Lynde observes, and the household that began with two silent siblings ends with a mother and daughter bound by the love Matthew helped create.
