From Inquiries into the Origin and Process of the Science of Heraldry in England by James Dallaway, p447

c. 1320

Surnames were additions necessary for the distinction of families, given to or assumed by their founders, and continued in hereditary progression. In a certain degree they were applied both by the roman and saxon invaders of this island, but were brought into more universal use by our norman ancestors.
