The sobriquet of Fitz-Aldin, given him from the great slaughter which he made of the Southron, and his reluctance to admit them to quarter. The sobriquet was adopted by him as a surname, and transmitted to his posterity. A novel by Sir W. Scott. (See chap. viii.)
A novel told in a series of letters by Sir Walter Scott. Sir Edward Hugh Redgauntlet, a Jacobite conspirator in favour of the Young Pretender, Charles Edward, is the hero. When George III. was crowned he persuaded his niece, Lilias Redgauntlet, to pick up the glove thrown down by the king's champion. The plot ripened, but when the prince positively refused to dismiss his mistress, Miss Walkinshaw- a sine quâ non with the conspirators- the whole enterprise was given up. General Campbell arrived with the military, the prince left Scotland, Redgauntlet, who embarked with him, became a prior abroad, and Lilias, his niece, married her brother's friend, Allan Fairford, a young advocate.
