Holborn
is not a corruption of Old Bourne, as Stowe asserts, but of Holeburne, the burne or stream in the hole or hollow. It is spelt Holeburne in Domesday Book, i. 127a; and in documents connected with the nunnery of St. Mary, Clerkenwell (during the reign of Richard II.), it is eight times spelt in the same way. (The Times; J. G. Waller.)
