The name Sedric has its origins in the Old English language, derived from the elements "siede" meaning "side" and "ric" meaning "power" or "ruler." It is believed to have emerged as a personal name during the Anglo-Saxon period in Britain, approximately between the 5th and 11th centuries.

One of the earliest recorded instances of the name Sedric can be found in the Anglo-Saxon Chronicle, a collection of annals documenting the history of the Anglo-Saxons. The chronicle mentions a Sedric who was a thegn (an aristocratic retainer) in the court of King Cnut the Great, who ruled from 1016 to 1035.

In the 12th century, a monk named Sedric was recorded as being part of the community at the Abbey of Bury St. Edmunds in Suffolk, England. This monastic community played a significant role in preserving and copying manuscripts during the Middle Ages.

Moving forward in history, a notable figure named Sedric was the Bishop of Chichester from 1180 to 1181. Although his time as bishop was brief, he left a mark on the ecclesiastical records of the time.

During the 13th century, a Sedric de Aumale was mentioned in the Pipe Rolls of Northumberland, which were financial records maintained by the English Exchequer. This suggests that the name was in use among the nobility of the time.

In the realm of literature, a character named Sedric appeared in the novel "Ivanhoe" by Sir Walter Scott, published in 1819. This fictional Sedric was a wealthy Saxon franklin (landowner) who played a role in the story set in medieval England.

While the name Sedric has fallen out of widespread use in modern times, it maintains a connection to its Old English roots and serves as a reminder of the linguistic and cultural heritage of the Anglo-Saxon period.
