[1] Lord Seton was a companion of King James IV of Scotland, and went with him on the expedition into England in 1513.
This campaign ended at the disastrous Battle of Flodden, where on 9 September, King James and Lord Seton were among the thousands of Scots who were killed.
They had one surviving son, who later succeeded as George Seton, 6th Lord Seton, and a daughter, Mariota (or Marion), who married, firstly Thomas, Master of Borthwick, secondly in 1530 she married Hugh Montgomerie, 2nd Earl of Eglinton, and thirdly, Alexander Graham of Wallacetown.
A pious lady, she continued to make gifts to Seton Church, and had new extensions built.
When her son, the young Lord Seton, came of age, she retired to the Convent of Saint Catherine of Siena, at Edinburgh.
