The Seton's were known as staunch supporters of the Stuart Monarchy, and to this end the family branches were strategically located as protectorates for the Royal residences.  The senior family at Seton was located just east of the capital of Edinburgh and the seat of power, and protected the main road into Scotland, Holyrood Palace in the city center, as well as the northern road coming from the Highlands to Linlithgow Palace.  The Seton's of Touch likewise were centrally located at Stirling, the second-most important Royal stronghold after Edinburgh, and kept a family presence there as protectorates.  The Seton's of Parbroath maintained their position nearby at Falkland Palace, and the Meldrum family ensured a Family presence in the north, flanking the city of Aberdeen.

Most of the existing Scottish Seton Families' members are descended from the following principle branches.  Note that each branch has cadets which have their own sub-lines of descendency.  Minor lines stem from the main family of Seton of Seton, however, the majority of the remaining families originate from the four oldest and longest established families.  Of these, the least documented family is that of the Seton's of Meldrum, from Aberdeen.  It can be said that their history is waiting to be uncovered, like an ancient trove of treasure long forgotten.
