Bacon, from the Anglo-Saxon bacan, to bake, to dry by heat. Some derive this surname from the Saxon baccen or buccen, a beech-tree. Upon the monument of Thomas Bacon, in Brome Church in Suffolk (Eng.), there is a beechtree engraven in brass, with a man resting under it. It appears, also, that the first Lord-keeper, Sir Nicholas Bacon, with his two wives, are represented in a similar manner.

BACON. A> seigniory in Normandy. According to the genealogy of the great Suflblk family of Bacon, one Grimbald, a relative of the Norman chieftain William de Wareune, came into England at the Conquest, and settled near Holt. His greatgrandson is stated to haA'e taken the name of Bacon. This was only a resimiption of an ancient Norman surname, which is still existing in the North of France. William Bacon, in 1082, endowed the abbey of the Holy Trinity at Caen. Taylor's Koman de Rou. The name is in the Battel Eoll, and in the H.R. it is written variously Bachun, Bacun, and Bacon. In some instances the surname may be a corruption of Beacon. From their connection with Bayeux, the Bacons were sometimes latinized De Bajocis.
