This French and English surname of ADAY was originally from the Hebrew personal name ADAM, which was borne according to Genesis, by the first man. It is of uncertain etymolology, and often said to be from the Hebrew ADAMA (earth). The Greek legend that Zeus fashioned the first human beings from earth. It was very popular as a given name throughout Europe during the Middle Ages. The name has numerous variant spellings which include ADER, ADAMI, DAMI, ADAMKSI, ADAMSKY, AZAM, ADAMINI, ADAMOLI, ADAMIK and ADEMIK, to name but a few. French, or rather Norman French, was the language of the aristocracy and the upper classes in England at the time fixed surnames were being developed, it is therefore not surprising that many of our well-known family names are derived from French words. Originally only Christian or personal names were used, and although a few came into being during the 10th century, surnames were not widely used until much later, when people began to realize the prestige of having a second name. A notable member of the name was Clement ADER (1841-1926) the French engineer and pioneer of aviation. In 1890 he built a steam-powered bat-winged aeroplane, the EOLE, which made the first powered take-off in history, but could not be steered and flew no more that 50 metres. 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. In the Middle Ages the Herald (old French herault) was an officer whose duty it was to proclaim war or peace, carry challenges to battle and messages between sovereigns; nowadays war or peace is still proclaimed by the heralds, but their chief duty as court functionaries is to superintend state ceremonies, such as coronations, installations, and to grant arms. Edward III (1327-1377) appointed two heraldic kings-at-arms for south and north, England in 1340. The English College of Heralds was incorporated by Richard III in 1483-84.
