Corduff (Irish: An Chorr Dhubh ) is a north western suburb of Dublin, Ireland. It is located near Blanchardstown and is part of the Dublin 15 postal district. At the last electoral count (2002–2006), the population was 4,821 of the 250,000 living in the 42 electoral divisions of Fingal. It is also a townland in the civil parish of Castleknock. Corduff is also a parish in the Blanchardstown deanery of the Roman Catholic Archdiocese of Dublin.
One of the earliest references to Corduff is in a document from the reign of Edward VI, dated 2 August 1547, which records a “lease to James Walshe of London, gent., of the rectory of Malahydert, County Dublin, and the tithes &c. in Malahydert, Culduff, Bossardston, Pasloweston...Tyrrolstown, Abbatiston...”
One striking thing about Corduff is the way its name has varied through the centuries. The form Culduff and significantly, Cooleduff (this last in the census of 1659) is the predominant one down to the early years of the 18th century. In the Civil Survey, compiled in the mid-1650s we find a notice of 'Colduff, ½ a plowland, 143 acres (0.58 km2), [property of] Will. Warren, Irish Papist ... There is upon ye premisses a stone house slated, one barne and stable tathct, severall cottages ... a small orchard and garden with a grove of ash trees, one mill in use worth Anno 1640 ten pounds per annum. The Tythes belong to ye Colledge of Dublin [i.e. Trinity College]. Bounded east with Davistowne, south with ye Toulchy, on ye west with Buzardstown, on ye north with Ballicolan”.
