Origin
Meaning and origin of Calderbank
The surname Calderbank originates from the northern counties of England, particularly Lancashire and Yorkshire, and dates back to the 12th century. It is a locational name derived from the Old English words "cald" meaning cold and "bank" referring to a riverbank or hillside, likely referring to a homestead situated near a cold stream or river.
One of the earliest recorded instances of the name appears in the Pipe Rolls of Lancashire in 1212, with a reference to Richard de Calderbanc. The surname is also found in the Lancashire Inquisitions of the 14th century, where it is spelled in various forms such as Calderbonk and Calderbanck.
The Calderbank name is closely associated with the town of Clitheroe in Lancashire, where a family of that name held lands and property from the 13th century onwards. John Calderbank, born in 1520, was a prominent figure in the town and served as a church warden and constable.
In the 17th century, the Calderbank family gained notoriety when Laurence Calderbank, born in 1635, was accused of witchcraft and executed during the infamous Pendle witch trials of 1612. This event has been widely documented in historical records and literature.
