Sept Alliances of the Seton's
In Scotland, beginning from the age of the Canmore dynasty and continuing until the Stuart's, septing was the alliance of a smaller family with that of a larger more prominent or powerful one usually within the same territorial juristiction.  Similar in many ways to an Allegiance to the Crown, Septing was not generally brought about by marriage, since the latter brought mutual blood ties between the two families.  Septs also had to abide by existing alliances stuck by the House to which they were forming an alliance with.

The practice of septing was not new or isolated to Scotland, throughout Europe and indeed in every cultural entity there have existed family alliances based upon political alliances, for protection, or other interests. In Scotland, the old the practice was also used to associate oneself or family with a Great House for elevation of social stature.  In modern times this is found to be useful for individuals or families which did not originate in Scotland, yet wish to associate themselves with a Scottish House to obtain a Scottish identity.  The process of Septing today still involves a formal Pledge of Allegiance, though the old practice of the mingling of blood, is one which is no longer used.

Some Ancient Septs of the Setons

Adinston of that Ilk
The Family long been the Hereditary Armour Bearers to the Head of House of Seton until the Seton forfeiture.

Stenhouse of Seton Village
The Family long resided in the village of Seton, now long erased from existence, and held their homes hereditarily under the Lords Seton and the Earls of Winton until after the Seton forfeiture of 1715.  They were at last removed from their ownership and presence on the Seton lands by Alexander MacKenzie who had acquired the lands of Seton fraudulently at auction, purchased after the Bankruptcy of the York Buildings Company who had acquired the estate and barony of Seton from the Crown after the Seton forfeiture.

Pringle of Greenknowe
The Family long leased the Tower at Greenknowe from the Seton's of Touch, who maintained the lands of Greenknowe and Gordon in the Borders region, before it's later acquisition by them over a century after it's construction.  They remained long in the service of the Seton's of Touch and Tullibody of Stirlingshire who were Hereditary Armour Bearers to the King.

de Quincy of Tranent
The Family that remained in Scotland after the Wars of Independence in the 14th century, which brought about the demised of the de Quincy family in Scotland, leased the Tower of Tranent for a time from the Lords Seton, as the Tower and the Barony of Tranent were previously a possession of the de Quincy's, along with that of Winton in nearby Pencaitland, and which all passed to the House of Seton who had generations earlier married a de Quincy heiress.

Falside of Tranent
The Family were originally a branch of the House of Seton, which took it's name from the estate of Falside.  A younger son of the early Seton's of Seton married the heiress of Falside and took that name and carried on that House.  As a result, of course, the family were strongly attached to the Seton's and known for their defense of the town of Tranent during the many wars in the region.  James Seton of Falside was noted during the funeral of Chancellor Seton, 1st Earl of Dunfermline in 1622.

Vallance of Tranent
The Family long leased the Tower at Tranent, and noted for their support of the Lords Seton, before acquiring the Tower outright.

Reid of Winchburgh
The Family long maintained the Castle and gardens of Niddry, West Lothian, for the Lords Seton and Earls of Winton.  What became of the Reids afterwards remains a cloudy history, though they had maintained a presence in Winchburgh after it's acquisition by the Hope Family, to which the 3rd Earl of Winton sold Niddry Castle, along with Winchburgh and Kirkliston, after his son's imprisonement for invovlement in Jacobite activities.  It appears that the Reids of Winchburgh also emigrated to Ulster, Ireland, in the early part of the 18th century.  There is also a noted marriage which brought about the family of Reid-Seton's.

Modern Sept of the Setons

Jarosz, Baron Kirkliston
The Family originally from the Carpathians, in Hungarian Transylvania.  In 2002 Andrew  Jarosz (Jaross otherwise) had acquired the former Seton feudal barony of Kirkliston (the barony lands lies on the Almond River, near Kirkliston village) by Feu Assignation from Adrian Hope of Hopetoun, Marquis of Linlithgow.  Thereafter he has petitioned for permission to be considered as a Sept of the House of Seton, being a Baron officially recognized on behalf of the Crown of Scotland, and the barony of Kirkliston originally a Seton barony, re-granted in 1618 to George Seton, Earl of Winton.  The Jarosz's of Kirkliston may be considered as modern Sept of the House of Seton.
