Originally the coat of arms identified the wearer, either in battle or in tournaments. Completely covered in body and facial armour the knight could be spotted and known by the insignia painted on his shield, and embroided on his surcoat, the draped garment which enveloped him. Bewteween the 11th & 15th centuries it became customary for surnames to be assumed in Europe, but were not commonplace in England or Scotland before the Norman Conquest. They are to be found in the Doomsday Book of 1086. Those of gentler blood assumed surnames at this time, but it was not until the reign of Edward II (1307-1327) that second names became general practice for all people. Many factors contributed to the establishment of a surname system. For generations after the Norman Conquest a veryfew dynasts and magnates passed on hereditary names, but the main of the population, with a wide choice of first names out of Celtic, Old English, Norman and Latin avoided ambiguity without the need for a second name. As society became more stabilized, there was property to leave in wills, the towns and villages grew and the labels that had served to distinguish a handful of folk in a friendly village were not adequate for a teeming slum where perhaps most of the householders were engaged in the same monotonous trade, so not even there occupations could distinguish them, and some first names were gaining a tiresome popularity, especially Thomas after 1170. the hereditary principle in surnames gained currency first in the south, and the poorer folk were slower to apply it. By the 14th century however, most of the population had acquired a second name.
The name has many variant spellings which include Gymer, Gymar and Guylmer.
