The surname of ACE was a baptismal name 'the son of Ascer' a very ancient personal name. Early records mention Azore (without surname) listed as a tenant in the Domesday Book of 1086. In 1086 the compilation of the Domesday Book was ordered by William the Conqueror (1027-87), king of England from 1066. He was born in Failaise, the bastard son of Robert, Duke of Normandy, by Arlette, a tanner's daughter. On his father's death in 1035, the nobles accepted him as a duke. When Edward the Confessor, king of England died in 1066, William invaded England that Autumn, on 14th October, 1066 killing Harold (who had become King). English government under William assumed a more feudal aspect, the king's tenants-in-chief and all title to land was derived from his grants, and the Domesday Book contains details of the land settlements, and the names of the owners of such. Asser (without surname) was canon of St. David's in 1202, County Lancashire. William Ascer of Lincolnshire, was documented in the year 1273. William Asser was rector of Aylmerton, in the County of Norfolk in 1397. John Adams and Phillipa Asser were married in County Hereford in the year 1671. Over the centuries, most people in Europe have accepted their surname as a fact of life, as irrevocable as an act of God, however much the individual may have liked or disliked the surname, they were stuck with it, and people rarely changed them by personal choice. A more common form of variation was in fact involuntary, when an official change was made, in other words, a clerical error. Among the humbler classes of European society, and especially among illiterate people, individuals were willing to accept the mistakes of officials, clerks and priests as officially bestowing a new version of their surname, just as they had meekly accepted the surname they had been born with. In North America, the linguistic problems confronting immigration officials at Ellis Island in the 19th century were legendary as a prolific source of Anglicization. The name is also spelt Atze, Atz and Azzi. In the Middle Ages heraldry came into use as a practical matter. It originated in the devices used to distinguish the armoured warriors in tournament and war, and was also placed on seals as marks of identity. As far as records show, true heraldry began in the middle of the 12th century, and appeared almost simultaneously in several countries of Western Europe.
