Lady Amabel Yorke was the elder daughter of Philip Yorke, 2nd Earl of Hardwicke, and his wife Jemima Campbell, 2nd Marchioness Grey, 4th Baroness Lucas. Their family seats were Wrest Park, Bedfordshire, and Wimpole Hall, Cambridgeshire, both of which had parks that were remodelled by Capability Brown with Amabel being privy to the design decisions. She was, then, rather well-informed on matters of landscape gardening, and her 37 volumes of diaries contain countless accounts of visits to the seats of her friends and family, where she sometimes notes follies and garden ornaments.
