Another stop on a Sheffield day trip with my guide for the day Kaplan 
Until the 17th century the name Sheaf was written as Scheth or Sheath. Sidney Oldall Addy equates the origins of this word with the Old English shed (as in water-shed) or sheth, which mean to divide, or separate. Historically, the Sheaf—along with its tributaries the Meers Brook and the Limb Brook—formed part of the border separating the Anglo-Saxon kingdoms of Mercia and Northumbria; it remained on the border between Yorkshire and Derbyshire into the 20th century. The city of Sheffield derives its name from the Sheaf.
The River Sheaf was originally culverted in the 1860's.
