Newland Archer's fiancée, then wife. Raised to be a perfect wife and mother, she follows and perfectly obeys all of society's customs. Mostly, she is the shallow, uninterested and uninteresting young woman that New York society requires. When they are in St. Augustine, though, May gives Newland a rare glimpse of the maturity and compassion he had previously ignored. She offers to release him from their engagement so he can marry the woman he truly loves, thinking he wants to be with Mrs. Rushworth, a married woman with whom he had recently ended a love affair. When he assures May that he loves only her, May appears to trust him, at least at first. Yet after their marriage, she suspects that Newland is Ellen's lover. Nonetheless, May pretends to be happy before society, maintaining the illusion that she and he have the perfect marriage expected of them. Her unhappiness activates her manipulative nature, and Newland does not see it until too late. To drive Ellen away from him, May tells Ellen of her pregnancy before she is certain of it. Yet there still is compassion in May, even in their loveless marriage's long years after Ellen's leaving. After May's death, Newland Archer learns she had always known of his continued love for Ellen; as May lay dying, she told their son Dallas that the children could always trust their father, Newland, because he surrendered the thing most meaningful to him out of loyalty to their marriage.
