(Note: Some sites state that Christopher Seton III's parents were John de Seton and Erminia Lascelles. However, this book, and my other research indicates Christopher Seton II is the father of Christopher Seton III and that John de Seton was the name of one of his brothers and of his uncle. More research is needed.)
SIR CHRISTOPHER SETON II. Sir Christopher Seton succeeded his pious father, and married Agnes, daughter of Patrick, Earl of March. He was a valiant knight, and did many brave deeds against the English when the crown of Scotland was in dispute between Bruce and Balliol. He was a friend and companion of the national hero, Sir William Wallace, and when driven off" his own lands by the enemy, took refuge with forty followers in Jedburgh Forest, "ay awating his tyme contrare the Englishmen," says Maitland. He was finally killed at the battle of Dillicarew, on the 12th of June, 1298, leaving two sons, Christopher and John.
SIR CHRISTOPHER SETON III. Sir Christopher Seton III succeeded his unfortunate but gallant father in these troublous times of the War of Independence. He was knighted by King Robert Bruce, and for his courtesy and valor was called by the common people, with whom he was a favorite, Good Sir Chrystell He is mentioned by Lord Hailes (Annals, II., 2) as one of the twenty "chief associates of Bruce in his arduous attempts to restore the liberties of Scotland." He is there styled Christopher Seton of Seton.
In 1301, when Sir Christopher was twenty-three years old, he married Lady Christian Bruce, sister of the heroic Robert. She was the daughter of Robert Bruce, Lord of Annandale, and of Margaret, heiress of Niel, Earl of Carrick.
At the disastrous battle of Methven, near Perth, on June 19, 1306, soon after Bruce' s coronation, the Scottish chiefs were defeated by Aylmer de Valence, Earl of Pembroke, and "the king was thrice unhorsed, and once so nearly taken, that the captor, Sir Philip De Mowbray, called aloud that he had the new-made king, when Sir Christopher Seton felled Mowbray to the earth and rescued his master."
The large two-handed sword, wielded on this occasion by our common ancestor, is now in the possession of George Seton, Esq., of Edinburgh, Representative of the Setons of Cariston.
***The historian Tytler says: "So dear to King Robert was the memory of his faithful friend and fellow warrior, that he afterwards erected on the spot where he was executed a little chapel, where mass was said for his soul." The widow of Sir Christopher was really the one who built this chapel for her husband, in honor of the Holy Cross; but her royal brother so generously endowed it by a charter dated at Berwick-on-Tweed, the last day of November 1323, that he is sometimes called the founder. This memorial chapel stood on a natural eminence just outside of the town walls, which was ever after called "Chrystell's Mount", and, by corruption, "Kerstie's Mount". It was a beautiful little Gothic building of oblong shape, cornered by pointed buttresses, and having a richly decorated oriel window. It was further endowed with a small portion of the surrounding land. Sir Richard Maitland, our earliest family historian, who lived before the downfall of the Old Religion in Scotland, tells us that he had sundry times held in his hand and read the king's charter endowing the chapel, that he had heard mass there, and that it was standing whole and entire in the year 1552. The chapel was closed after the establishment of the New Religion in Scotland, and its endowments were secularized. It remained standing for nearly two centuries, a forlorn protest against the spoliation, until it was torn down in a panic by the townspeople in 1715, to build a wall and rampart against an expected attack of the Jacobite insurgents. A Presbyterian church was raised in 1838 on what is still called "The Chrvstal Mount"; and when the excavations were being made, traces of the foundation of the chapel were discovered, and "many of the stones, but all without ornaments, are still to be discerned in the neighboring dykes." A few of these were collected and set up, with a well-meaning but inelegant inscription, within his private burial ground by the late Major James Adair in 1840.
