The first written record of Thames Ditton is in a charter dated 983 when King Æthelred the Unready granted to Æthelmær, his minister, nine hides ("cassati") at Thames Ditton, Surrey. In "The Cartulary of the Abbey of Eynsham Transaction", King Æthelred sent to Eynsham Abbey confirmation of the foundation (in 1005) by Æthelmær, the endowment including 20 hides at Esher, Surrey (granted by Beorhthelm, bishop, to Æthelweard, and bequeathed by Æthelweard to his son, Æthelmær); and land at Thames Ditton, Surrey, among several other items.
