The surname Westerdale is believed to have originated in England, specifically in the northern counties of Yorkshire and Durham. It is a locational surname, derived from the place name "Westerdale," which itself is an Old Norse and Old English compound word meaning "western valley."
Westerdale is thought to have first emerged as a surname in the 12th or 13th century, as people began to adopt hereditary surnames based on their place of origin or residence. The earliest known recorded instance of the name dates back to 1273, when a Robert de Westerdal was mentioned in the Hundred Rolls of Yorkshire.
In the Domesday Book of 1086, a survey of land and property commissioned by William the Conqueror, there are several references to places with names similar to Westerdale, such as Westredene and Westredal, which may have been early precursors to the modern spelling.
One of the earliest known individuals with the surname Westerdale was John Westerdale, a merchant and alderman of York who lived in the late 14th century. Another notable bearer of the name was Sir Ralph Westerdale, a soldier and knight who fought in the Wars of the Roses during the 15th century.
During the 16th and 17th centuries, the Westerdale surname began to spread beyond its northern English origins. In 1602, a Thomas Westerdale was recorded as living in the parish of St. Martin-in-the-Fields in London. Around the same time, the variant spelling "Westerdaile" appeared in records from Gloucestershire.
