Meaning and origin of Haselby
The surname HASELBY is of English origin, originating from the Yorkshire region of England during the medieval period. It is a locational surname, derived from the place name "Haselby," which was a small hamlet or village in the East Riding of Yorkshire.
The name HASELBY is believed to have originated from the Old English words "hæsel" meaning "hazel" and "by" meaning "a farmstead or village." This suggests that the name likely referred to a settlement or farmstead situated near or surrounded by hazel trees.
One of the earliest recorded instances of the surname HASELBY can be found in the Domesday Book, a comprehensive record of landholdings and population compiled in 1086 under the reign of William the Conqueror. In this document, the place name "Haselby" is mentioned, indicating the existence of the settlement and its inhabitants at that time.
During the 13th century, a notable individual named Richard de Haselby was recorded as a cleric and theologian who served as the Chancellor of the University of Oxford. He was born around 1260 and played a significant role in the academic and religious institutions of his era.
In the 14th century, a family bearing the surname HASELBY was documented as residing in the village of Haselby in Yorkshire. One member of this family, John Haselby, was recorded as a landowner and farmer in the area during the late 1300s.
Moving into the 15th century, a prominent figure named William Haselby was mentioned in historical records as a wealthy merchant and ship owner based in the city of York. He was active in trade and maritime ventures during this period.
Another notable individual with the surname HASELBY was Sir Thomas Haselby, who lived in the 16th century and served as a member of the English gentry. He was a landowner and held various positions of authority in his local community.
Throughout the centuries, the surname HASELBY has undergone various spelling variations, including Hasilby, Hasylby, and Hasselby, reflecting the changing orthography and regional dialects of the English language over time.
While the surname HASELBY is not among the most common surnames in modern times, its roots can be traced back to the medieval period in the Yorkshire region of England, where it originated as a locational name derived from the place name "Haselby."

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
