Caroline, Countess of Cranbrook, addressed as Lady Cranbrook, is an English aristocrat, titled by being the wife of Gathorne Gathorne-Hardy, 5th Earl of Cranbrook, and campaigner on food quality issues.
She was born Caroline Jarvis in Lincolnshire on 18 December 1935. Her father was Colonel Ralph George Edward Jarvis and her mother Antonia Mary Hilda Meade.
She married the Earl of Cranbrook on 9 May 1967, and took up the married name Caroline Gathorne-Hardy. Their early home was in a jungle area of Malaya, where her husband worked as a zoologist. After three years, they took up residence at his family seat, Great Glemham House, Great Glemham, Saxmundham, Suffolk. She ran the estate farm and raised their three children. When her husband inherited the Earldom of Cranbrook from his father, on 22 November 1978, she became a Countess.
