This surname of AREHART was of the baptismal group of surnames meaning 'the descendent of Ehrlich' composed of the elements ERA (honour) and HARD (brave). The name has also been adopted by Ashkenazic Jews and is also spelt ERHARDT, ERARD and ERHARD. The first hereditary surnames on German soil are found in the second half of the 12th century, slightly later than in England and France. However, it was not until the 16th century that they became stabilized. The practice of adopting hereditary surnames began in the southern areas of Germany, and gradually spread northwards during the Middle Ages. When traditional Jews were forced to take family names by the local bureaucracy, it was an obligation imposed from outside traditional society, and people often took the names playfully and let their imaginations run wild by choosing names which corresponded to nothing real in their world. No one alive today can remember the times when Jews took or were given family names (for most Ashkenazim this was the end of the 18th century or the beginning of the 19th) although many remember names being changed after emigration to other countries, such as the United States and Israel in recent years. The origin of badges and emblems, are traced to the earliest times, although, Heraldry, in fact, cannot be traced later than the 12th century, or at furthest the 11th century. At first armorial bearings were probably like surnames and assumed by each warrior at his free will and pleasure, his object being to distinguish himself from others. It has long been a matter of doubt when bearing Coats of Arms first became hereditary. It is known that in the reign of Henry V (1413-1422), a proclamation was issued, prohibiting the use of heraldic ensigns to all who could not show an original and valid right, except those 'who had borne arms at Agincourt'. The College of Arms (founded in 1483) is the Royal corporation of heralds who record proved pedigrees and grant armorial bearings. The bulk of European surnames in countries such as England and France were formed in the 13th and 14th centuries. The process started earlier and continued in some places into the 19th century, but the norm is that in the 11th century people did not have surnames, whereas by the 15th century they did.
