The history of the last name Sizemore

The surname Sizemore is of English origin, with its roots tracing back to the Middle Ages. It is believed to have originated from the region of Gloucestershire, where it was likely derived from a place name or a descriptive term related to a person's occupation or physical characteristics.

One theory suggests that Sizemore may have evolved from a combination of the Old English words "sise" and "mor," meaning "ample" and "moor" respectively. This could indicate that the name was initially used to describe someone who lived on or near a large moor or heath.

Another possibility is that Sizemore was derived from the Old English word "sizer," which referred to a person responsible for measuring or assessing quantities, perhaps in a trade or agricultural setting. This occupational surname may have been given to someone who worked as a measurer or assessor.

While the name Sizemore does not appear in the Domesday Book, one of the earliest recorded instances can be found in the Pipe Rolls of Gloucestershire from 1195, where a person named Richard de Sysemore is mentioned. This spelling variation highlights the name's evolution over time.

In the 17th century, the name Sizemore was also found in various parish records and court documents across England, indicating its continued use and spread throughout the country.

During the colonial era, several individuals with the Sizemore surname migrated to the Americas, contributing to the name's further dissemination. One such example is John Sizemore (1620-1698), an early settler in Virginia who established a prominent family lineage in the region.
