Old Mortality, Volume 1.

The origin of Old Mortality, perhaps the best of Scott's historical romances, is well known. In May, 1816, Mr. Joseph Train, the gauger from Galloway, breakfasted with Scott in Castle Street. He brought gifts in his hand,—a relic of Rob Roy, and a parcel of traditions. Among these was a letter from Mr. Broadfoot, schoolmaster in Pennington, who facetiously signed himself Clashbottom. To cleish, or clash, is to flog, in Scots. From Mr. Broadfoot's joke arose Jedediah Cleishbotham, the dominie of Gandercleugh; the real place of Broadfoot's revels was the Shoulder of Mutton Inn, at Newton Stewart. Mr. Train, much pleased with the antiques in the den of Castle Street, was particularly charmed by that portrait of Claverhouse which now hangs on the staircase of the study at Abbotsford. Scott expressed the Cavalier opinions about Dundee, which were new to Mr. Train, who had been bred in the rural tradition of Bloody Claver'se.
Might he not, asked Mr. Train, be made, in good hands, the hero of a national romance as interesting as any about either Wallace or Prince Charlie? He suggested that the story should be delivered as if from the mouth of Old Mortality. This probably recalled to Scott his own meeting with Old Mortality in Dunnottar Churchyard, as described in the Introduction to the novel.
The account of the pilgrim, as given by Sir Walter from Mr. Train's memoranda, needs no addition. About Old Mortality's son, John, who went to America in 1776 (? 1774), and settled in Baltimore, a curious romantic myth has gathered. Mr. Train told Scott more, as his manuscript at Abbotsford shows, than Scott printed. According to Mr. Train, John Paterson, of Baltimore, had a son Robert and a daughter Elizabeth. Robert married an American lady, who, after his decease, was married to the Marquis of Wellesley. Elizabeth married Jerome Bonaparte! Sir Walter distrusted these legends, though derived from a Scotch descendant of Old Mortality. Mr. Ramage, in March, 1871, wrote to Notes and Queries dispelling the myth.
