Mrs. Campbell is the wife of Colonel Campbell and the mother of Mrs. Dixon. She is a friendly, warm-hearted woman. She and her husband took in Jane Fairfax, educating her alongside their daughter, and as long as they live, she will have a home with them.
Jane decides to visit her aunt and grandmother rather than join the Campbells at Mr. Dixon's estate Baly-craig, and when their three month visit is extended, she again refuses their offer to pay for her travel expenses and join them. Later, the Campbells and Dixons learn of her secret engagement to Frank Churchill. Jane stays with the Campbells until she marries.
