Horrocks

Horrocks is an English surname of patronymic origin, meaning 'son of Horrock'. The personal name Horrock is a diminutive of Horrocks, which itself is a variant of the Old English personal name 'Horroc' or 'Horrocg'. This name is thought to be derived from an Old English word 'horh' meaning 'dirt' or 'filth', possibly used as a nickname for someone with a dirty appearance or occupation, or perhaps referring to a place name. Alternatively, it could be a variant of the Norse name 'Hrókr', meaning 'rook' or 'crow', which was brought to England by the Vikings.

The surname is particularly prevalent in Lancashire, England, suggesting a strong regional origin. Early records show variations such as Horrocks, Horrock, Horrox, and Horrocks. The name has been in use as a surname since at least the 13th or 14th century, evolving through the Middle Ages.
