Etymology

'Dyda's cottage', v. ing 4 , cot . On the OE  pers.n. Dyd (d )a cf. Didbrook (9supra ), 4 miles away over Dumbleton Hill; the identification of Dydinc cotan is not certain, as it appears in a Pendock (Wo) charter; the place appears, however, to have been a separate unit from Pendock, and to have been a dependency of Overbury (Wo 153), 3 miles WNW of Didcot; Overbury is included in the charter (Grundy (Wo) 29).
