The surname Sellon is of Anglo-Norman origin, deriving from the French words "sel" meaning salt and "lône" meaning a piece of land. It is believed to have originated in the 11th century from the areas of Normandy and Brittany in northern France. The name likely referred to an area of land where salt was produced or traded.
One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, where it appears as "Selun" in the county of Dorset, England. This suggests that the name had already been introduced to England by Norman settlers shortly after the Norman Conquest in 1066.
In the 13th century, the name appears in various records with spellings such as "Sellun," "Sellon," and "Sellen." During this time, there are references to individuals with the name holding land or positions of importance in places like Sussex, Hampshire, and Wiltshire.
One notable figure was Sir John Sellon, who was born in Wiltshire in the late 14th century and served as a Member of Parliament for the county in 1402. Another was William Sellon, a merchant and alderman in the city of London, who lived in the early 15th century.
In the 16th century, the name can be found in records associated with the town of Sellon, which was located in the county of Shropshire. This may have been a place name derived from the surname itself.
Other historical figures with the surname include Walter Sellon, a prominent lawyer and landowner in Gloucestershire during the late 16th century, and Edward Sellon, an English playwright and poet who was active in the early 17th century.
As the name spread across England and into other parts of the British Isles, it also took on various regional spellings and variations, such as "Sellone," "Selloun," and "Sellens."
