Note: Ekwall (The Oxford Dictionary of English Place Names, 1936) ascribes the Berkshire place names to the OE 'cocc' (hill) and 'hamm' (land in the bend of a river), noting that "Cookham stands in the bend of the Thames at a hill called 'Cocdun'." In EPNS 49, Gelling thinks that this is the royal manor of Cookham (borne out by later spellings 'Coukham' and 'Cookham') believing that the 12th- and 13th-century scribes of certain relevant documents substituted 'cocc-' for 'cōc-' since 'cocc' (hill) and 'cocc' (cock) are fairly common in place names, whereas 'cōc' seems to occur only in this name. She thinks the etymology is apparently 'cook village,' noting that it is unusual and comparing it to Harpham ('harp village'), suggesting that both names refer to villages known for a particular activity.
