Recorded in the spellings of Lauder and Lauderdale, this is a famous Scottish locational surname. As Lauder it originates from the village of Lauder in the county of Berwickshire, and as Lauderdale from a name for the western district of the same county of Berwickshire. The translation of the place name and hence the later surname is believed to be from the French-Breton pre 7th century word "laour", meaning a trench or ditch. The surname is one of the first recorded in Scotland, and early examples taken from authentic rolls and registers of the medieval period include: William de Lawedre, the sheriff of Perthshire in the reign of King Alexander IIIrd of Scotland (1249 - 1286), Alan de Lawadyr, who witnessed a charter by Stephen Fleming, master of the hospital of Soltre in 1426, and Johannes Lathirdale, a notary public, in the city of Glasgow in 1472. Other recordings include Sir David Luthirdale, archdeacon of Dunkeld in 1477, whilst William Lauder, given as being a literary forger, died in 1771. The first recorded spelling of the family name is shown to be that of Sir Robert de Lauedre. This was dated 1250, in the register of the Abbey of Dryburgh. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
