The Porteous family is a Scottish Borders armigerous family.
The earliest records for members of the Porteous family in Peeblesshire date back to the early part of the fifteenth century.
The earliest possible reference, according to Lord Lyon King of Arms in Edinburgh, is to a Guillaume Porteuse (later William Porteous), who arrived from Normandy c 1400 under the patronship of the wealthy Fraise family (later to become the Frasers). They had already settled in parts of lowland Scotland, having been granted lands by the King.
The early meaning of the name Porteuse (from the French) was indeed possibly of 'courier' or 'messenger'. But in Scotland, they turned their hand to other trades. In the days when the glens and hamlets of Tweeddale and, later, Annandale were much more densely populated than today, they seem to have pursued various occupations – from millers and blacksmiths to ministers of religion.
The home of early members of the Porteous family for many hundreds of years was Hawkshaw in Peeblesshire. The link to modern day families is as yet unproven. There is some doubt as to how long the family had held the ancestral family home, but it is certain that there a castle of sorts at Hawkshaw, probably built as no more than a small fortified keep, and intended as a watch tower where a signal fire could be lit to warn of approaching danger. A line of these so-called Peel towers was built in the 1430s across the Tweed valley from Berwick to its source, as a response to the dangers of invasion from the English borders. Hawkshaw was one of over two dozen of these in Peeblesshire alone.
