Last name: Sanford. This is a topographical and locational name of ancient origins. It derives from the Olde English Sand-Forda, meaning one who dwelt at or was responsible for the Sandy Ford, or from residence at one of the several villages called Sandford or Sandyford found from Westmoreland to Devon.
In its full length it is often recorded as 'Parkinson' and less so as 'Perkinson'. There is an occasional secondary origin from the French 'parc'. As such this was an occupational surname for a keeper of royal hunting grounds, known as 'The Parks'. Early examples of the recordings include Robert Parkyn of Stafford in the County Rolls of 1327, and John Perkyn of Somerset, in the Hundred Rolls of 1380.
