Clan Hay, sometimes found in records as de la Haye or simply Hay of Erroll, is one of the most distinguished noble families in Scottish history. Their name appears at the heart of Scotland's constitutional and military story across nearly nine centuries, and the office they held — Hereditary High Constable of Scotland — remains one of the oldest heritable dignities in the United Kingdom to this day. For those tracing Scottish ancestry through Aberdeenshire, Perthshire, or the Mearns, the name Hay carries particular resonance.
Where Does the Hay Name Come From?
The Hay family is generally traced to a Norman ancestor named William de la Haye, who arrived in Scotland during the reign of David I in the twelfth century. The de la Haye family are believed to have originated from La Haye in Normandy, and like many Norman settlers of that era they integrated quickly into Scottish noble society through royal grants and loyal service. The anglicised form Hay became established across eastern Scotland, particularly in Perthshire, the Mearns, and Aberdeenshire, where the family's landholdings grew considerably over succeeding generations.
William de la Haye received the lands of Erroll in Perthshire, which became the ancestral heartland of the senior branch of the family. It is from this estate that the principal line of Clan Hay took their title, becoming Earls of Erroll, a dignity that has descended in an unbroken line to the present day and which carries with it the ancient office of High Constable.
What Is the Hay Clan Motto?
The Clan Hay motto is Serva Jugum, a Latin phrase meaning Keep the Yoke. It is a motto that has generated considerable discussion over the centuries. On one level it speaks to duty, obligation, and the acceptance of responsibility — the image of bearing a yoke without complaint. On another it may reflect the clan's enduring role as servants of the Crown in the capacity of High Constable, a position that literally required them to maintain order and uphold royal authority. The motto is paired with a crest depicting an ox yoke between two sprigs of grain, imagery that reinforces the agricultural and heraldic symbolism of the motto.

The Battle of Luncarty and the Origin Legend
Like many Scottish clans, the Hays carry an origin legend that, while difficult to verify historically, speaks powerfully to the character they have traditionally claimed. According to the story, a peasant named Hay and his two sons played a decisive role in repelling a Danish or Norse invasion at the Battle of Luncarty in Perthshire, traditionally dated to around 980. Armed with little more than an ox yoke, Hay is said to have rallied fleeing Scottish troops and turned the battle in their favour. As a reward, the king granted him as much land as a falcon could fly over before landing — and the bird reportedly landed at a place that became associated with the Hay estates in Perthshire.
Whether this account reflects actual events or is a later embellishment meant to explain the clan's heraldic imagery is uncertain. The ox yoke in the crest, the motto Serva Jugum, and the association with Luncarty all fit together too neatly to be entirely coincidental, and historians have generally treated the legend as a possible folk memory of real early medieval service, if not a literal account of events.
Hereditary High Constables of Scotland
The most significant distinction held by Clan Hay is undoubtedly the office of Hereditary High Constable of Scotland. This position, which passed to the Earls of Erroll from the thirteenth century onward, placed the head of the clan at the apex of Scotland's military and ceremonial hierarchy. The High Constable ranked above all other officers of state except the monarch, with precedence even over the hereditary marshals and the great officers of the royal household.
In practical terms the High Constable was responsible for maintaining order at coronations, parliaments, and great assemblies. The office carried considerable authority and, at times of crisis, real political weight. The Hays used this position intelligently across the centuries, navigating the turbulent waters of Scottish and later British politics with considerable skill. They were not always on the winning side — several Earls of Erroll faced attainder, forfeiture, or exile at various points — but the office itself survived and the family eventually recovered their lands and dignity on each occasion.
The title and office continue today. The current Countess of Erroll holds the position of Hereditary High Constable, making it one of the few great mediaeval offices still extant in its hereditary form anywhere in the British Isles. For those with Hay blood, this is a remarkable living connection to a very ancient tradition. Clans with similarly deep ties to the north-east of Scotland, such as Clan Keith, who served as Hereditary Marshals, and Clan Hepburn, whose story is also woven into the fabric of Scottish nobility, share some of the same historical landscape as the Hays.
Slains Castle and the Aberdeenshire Coastline
The most dramatic of the Hay ancestral properties is undoubtedly Slains Castle on the Aberdeenshire coast, north of Aberdeen near the village of Cruden Bay. The castle that stands today — or rather its substantial ruin — is not the original Slains Castle, which was located further south and was demolished on the orders of James VI after the ninth Earl of Erroll supported the Catholic earls in their rebellion of the 1590s. The present ruin dates from the late sixteenth and seventeenth centuries and was significantly extended in subsequent generations.
Slains Castle is perched at the very edge of the cliff above the North Sea, and its exposed position on the Aberdeenshire coastline gives it an atmosphere of considerable drama. It is perhaps best known today as one of the sites that is claimed to have inspired Bram Stoker's Dracula — Stoker visited the area in the 1890s when staying nearby at Cruden Bay and is thought to have drawn on the castle's Gothic silhouette and remote setting. Whether or not Stoker found his inspiration there, the castle's ruined state and coastal setting make it one of the most evocative clan sites in Scotland. The Hays lost the property in the early twentieth century and it has been a ruin since the roof was removed in 1925.
Clan Hay in the Reformation and the Covenanting Era
The sixteenth and seventeenth centuries were turbulent times for most Scottish noble families, and the Hays were no exception. Several Earls of Erroll maintained Catholic sympathies during the Reformation period, which brought them into conflict with both the Presbyterian Kirk and with the Crown at various points. The ninth Earl was among the Catholic nobles who entered into correspondence with Spain in the 1590s, leading to the demolition of the original Slains Castle as a punitive measure by James VI.
Later generations navigated the Covenanting conflicts and the Jacobite risings with varying degrees of success. The Hays broadly inclined toward the Stuart cause, and several members of the family faced consequences for their loyalties after the failure of the 1715 and 1745 risings. The family's Catholic faith, which persisted in some branches well beyond the Reformation, added another layer of complexity to their political position in post-Union Scotland.
Hay Septs and Spelling Variations
Those researching the Hay name in genealogical records will encounter a range of spellings depending on the period and the region. Hay, Haye, de la Haye, and Hays are all found in historical documents, and some researchers also connect the name Haye to branches that later simplified to Hay in anglicised records. The Irish surname Hayes, while related to different Gaelic roots in most cases, occasionally overlaps with Scottish Hay families who settled in Ulster during the plantation period.
Septs of Clan Hay include Constable, Constable-Maxwell, Gifford, and Yule, among others. For those carrying these names who are researching a possible connection to the Hay clan tradition, the records of the Lord Lyon King of Arms in Edinburgh and the resources held by the Court of the Lord Lyon are the most reliable starting points for establishing a formal clan connection.
