Lay of the Last Minstrel
An aging minstrel seeks who hospitality at Newark Castle and in recompense tells a tale of a sixteenth-century Border feud. In the poem, Lady Margaret Scott of Buccleuch, the "Flower of Teviot" is beloved by Baron Henry of Cranstown an ally of the Ker Clan, but a deadly feud exists between the two border clans of Scott and Carr/Ker, which has resulted in the recent murder of Lady Margaret's father, Sir Walter Scott of Buccleuch by the Kers on the High Street in Edinburgh. Maragaret's widowed mother – Lady Janet – hates the Ker clan as a result, and is adamant in refusing her consent to any suggestion of marriage between the lovers. Summary by Wikipedia
