This Spanish surname of ARROYO was a topographic name for someone who lived near a stream or irrigation channel, originally derived from the Spanish word ARROYO meaning water-course. Surnames derived from placenames are divided into two broad categories; topographic names and habitation names. Topographic names are derived from general descriptive references to someone who lived near a physical feature such as an oak tree, a hill, stream or a church. Habitation names are derived from pre-existing names denoting towns, villages and farmsteads. Other classes of local names include those derived from the names of rivers, individual houses with signs on them, regions and whole countries. 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. The sun depicted in the arms denotes power and splendour. In the 8th century, Spain fell under the control of the Moors, and this influence, which lasted into the 12th century, has also left its mark on Hispanic surnames. A few names are based directly on Arabic personal names. The majority of Spanish occupational and nickname surnames, however, are based on ordinary Spanish derivatives.
