Recorded in many spellings from Farrar, Ferrara and Ferrari, to Herrers, Farreres, and Ferreira, this ancient and noble surname is either occupational or residential. It is a derivative of the Roman (Latin) 'Ferrum', meaning iron, and is recorded in almost every European country in the appropriate spelling, making it international in origin. The surname describes either an iron maker, or somebody who lived by or at an iron works. The surname has also derived from two villages in France called 'Ferrieres', places where iron ore was mined.
A number of followers of Duke William of Normandy, the conqueror of England in 1066, were from these villages. These people were rewarded with titles, (The earls of Derby), and estates in England, later called Newton Ferrers and Bere Ferrers.
