The name Brea is believed to have originated from the Old English word "bred," which means "broad" or "wide." This name can be traced back to the Anglo-Saxon period, which spanned from the 5th to the 11th century CE, in areas that are now part of modern-day England and parts of southeastern Scotland.

During the medieval period, the name Brea was commonly used as a surname or a descriptive nickname to refer to someone with a broad or sturdy build. It was not until later that the name gained popularity as a given name, particularly in the English-speaking world.

One of the earliest recorded instances of the name Brea can be found in the Domesday Book, a comprehensive survey of land and property conducted in England in 1086 by order of King William the Conqueror. The Domesday Book mentions several individuals with the surname "Bred" or "Brede," which is believed to be a variant of the name Brea.

Throughout history, there have been several notable individuals who bore the name Brea. One of the earliest recorded figures was Brea of Hereford, an English nobleman who lived in the 12th century and was known for his involvement in the Norman Conquest of England.

Another notable bearer of the name was Brea de Burgh, a 13th-century Anglo-Norman heiress and landowner who held significant properties in Ireland and England. She played a role in the Wars of the Roses, a series of civil wars fought between the Houses of Lancaster and York for the English throne.

In the 16th century, there was Brea Carey, an English courtier and favorite of Queen Elizabeth I. She was known for her wit and intelligence and was a prominent figure at the Elizabethan court.

Moving forward to the 19th century, Brea Drummond was a Scottish artist and painter who gained recognition for her landscape and portrait works. She was also an advocate for women's rights and education.

In more recent times, Brea Binder was a Canadian athlete and Olympic medalist in swimming, competing in the 1976 and 1984 Olympic Games.

While the name Brea has maintained its presence throughout history, it has remained relatively uncommon compared to other names of English origin. Nevertheless, its unique etymology and historical significance have contributed to its enduring appeal as a given name.
