The name Bradon is a variant of the English name Brandon, which is derived from the Old English words "brun" meaning "brown" and "dun" meaning "hill" or "down". It is believed to have originated as a surname in the Middle Ages, referring to someone who lived on or near a brown hill or down.

The earliest recorded use of the name Brandon dates back to the 12th century, when it appears in the Domesday Book of 1086, a record of landowners in England commissioned by William the Conqueror. The name was likely of Anglo-Saxon origin, but it gained popularity during the Norman conquest of England in the 11th century.

One of the earliest recorded individuals with the name Brandon was Brandon de Goushill, who lived in the 13th century and was a prominent landowner in Yorkshire, England. Another notable figure was Sir William Brandon, who served as Standard-Bearer to Henry V during the Battle of Agincourt in 1415.

In the 16th century, Charles Brandon, 1st Duke of Suffolk (c. 1484-1545), was a close friend and brother-in-law of King Henry VIII of England. He played a significant role in the English Reformation and was a influential figure in the Tudor court.

During the 17th century, Robert Brandon (c. 1610-1690) was an English Puritan minister and author who wrote several religious works, including "The Doctrine of Remission" and "A Treatise on Justification".

In the 19th century, John Raphael Brandon (1817-1877) was an English wood engraver and author who produced numerous illustrations for books and magazines. His work was highly influential in the development of wood engraving as an art form.

While the name Brandon has a long history, the variant spelling Bradon is relatively more modern and less common. However, it still carries the same meaning and historical significance as its parent name.
