The surname of ANGLESEY was a locational name 'of Anglesy in Wales' the dweller at an old Monastery. Local names derived from a place name indicating where the man held land, or the place from which he had come, or where he actually lived. Local surnames, by far the largest group, derived from a place name where the man held land or from the place from which he had come, or where he actually lived. These local surnames were originally preceded by a preposition such as "de", "atte", "by" or "in". The names may derive from a manor held, from working in a religious dwelling or from literally living by a wood or marsh or by a stream. Early records of the name mention Angleseia (without surname) 1242 Wales. Angleseya 1254 ibid. Thomas Anglesea of Wales was recorded in the year 1300, and Edward Anglesye of Yorkshire, was listed in the Yorkshire Poll Tax of 1379. Between the 11th and 15th centuries it became customary for surnames to be assumed in Europe, but they were not commonplace in England or Scotland before the Norman Conquest of 1066. They are to be found in the Domesday Book of 1086. Those of gentler blood assumed surnames at this time, but it was not until the reign of Edward II (1327-1377) that it became common practice for all people. As early as the year 1100, it was quite common for English people to give French names to their children, and the earliest instances are found among the upper classes, both the clergy and the patrician families. The Norman-French names used were generally the names most commonly used by the Normans, who had introduced them into England during the Norman Invasion of William the Conqueror in 1066. It has long been a matter of doubt when the bearing of coats of arms first became hereditary and it was not until the Crusades that Heraldry came into general use. Men went into battle heavily armed and were difficult to recognise. It became the custom for them to adorn their helmets with distinctive crests, and to paint their shields with animals and the like. Coats of arms accompanied the development of surnames, becoming hereditary in the same way.
