The surname Tweeddale originated in the Scottish Borders region, taking its name from the River Tweed and the valley it flows through, known as Tweeddale. The name is thought to have derived from the Brittonic word "Tuedion", meaning a border region or frontier.
The earliest recorded mention of the name Tweeddale dates back to the 12th century, with records of a land grant to Walter de Tweeddale in 1165. This suggests the name was well-established as a territorial designation by the medieval period.
