The given name Brysen has its origins in the Old English language, with roots tracing back to the 8th century AD. It is believed to be a variant of the name Bryson, derived from the Old English words "bry" meaning "to brew" and "sun" meaning "son." This suggests that the name may have referred to the son of a brewer or someone associated with the brewing profession.

In early medieval times, the name was predominantly found in the regions of present-day England and parts of Scotland. Historical records from this period reveal several variations of the spelling, including Brysan, Brysen, and Brisun.

One of the earliest documented references to the name Brysen can be found in the Anglo-Saxon Chronicle, a collection of annals chronicling the history of the Anglo-Saxons. The entry from the year 871 AD mentions a person named Brysen, who was a follower of the Viking leader Ivar the Boneless.

Throughout the Middle Ages, the name Brysen remained relatively uncommon but was occasionally encountered among the lower nobility and commoners of English and Scottish descent. Notable figures bearing this name include Brysen of Alnwick, a local landowner who lived in the 12th century in Northumberland, England.

During the Renaissance period, the name gained some prominence in literary works. One of the earliest examples is Brysen, a character in the 16th-century play "Gammer Gurton's Needle" by the English playwright William Stevenson.

In the 17th century, Brysen Meyrick (1623-1691) was a Welsh politician and Member of Parliament who served during the reign of King Charles II. Another notable figure was Brysen Hawthorne (1674-1738), an English merchant and explorer who wrote accounts of his travels to the East Indies.

Fast-forwarding to the 19th century, Brysen Pearce (1818-1892) was a renowned English architect and designer who contributed to the Gothic Revival movement. Additionally, Brysen Whiteley (1843-1921) was a prominent British industrialist and philanthropist known for his support of educational initiatives.
