Mr. John Hay Allen, as before stated, first appeared in literature in 1822. His volume of poems bore those names. Twenty years later, in 1842, the same gentleman edited, under the assumed name of John Sobieski Stolberg Stuart, the ‘Vestiarium Scoticum,’ the transcript from a MS. alleged to have been formerly in the Scots College at Douay; with a learned introduction and illustrative notes. This folio, at the time, made no particular sensation. It was followed, in 1845, by a work, in which the elder brother was assisted by the younger, namely, ‘Costume and History of the Clans,’ with three dozen lithographs, in imperial folio; the cheapest edition was priced at six guineas. Some were much dearer. Two years later, a work very different in intention, was published by the Roman Catholic publisher Dolman, of Bond Street, who had Blackwood of Edinburgh and London as his colleague. The title of this book was ‘Tales of the Last Century, or Sketches of the Romance of History between the years 1746 and 1846,’ by John Sobieski and Charles Edward Stuart. There is a dedication ‘To Marie Stuart, by her father and uncle.’ [Sidenote: _THE ROMANCE OF THE STORY._] As Sketches of the _Romance_ of History, the writers _might_ have meant that they were not dealing with _reality_. But such seemingly was not their meaning. They made a serious step towards asserting that the elder brother was rightful heir to the throne of the Stuarts; and that if Jacobites and Ultramontanists should ever be in search of such an heir, after upsetting the present ‘happy establishment,’ he was to be found at his lodgings, prepared to wear the crown, with Jacobite instincts and Ultramontane ferocity. Of course, this was not said in words. It is rather implied in the three sketches which make up the romance of ‘Tales of the Last Century.’ The Tales illustrate the claims of the Chevalier John Sobieski Stuart, after this fashion.――The ‘young Pretender’ married in 1772, Louise, Princess of Stolberg Gœdern, and grand-daughter of the Jacobite Earl of Aylesbury, who after his liberation from the Tower, in 1688, for his political principles, settled in Brussels, and there married (his second wife) a lady of the ancient family of Argentain. The daughter and only child of this marriage wedded with the Prince of Horne. Louisa of Stolberg, the youngest child of the last named union, married Charles Edward in 1772, when she was not yet twenty, and he was fifty-two. According to the ‘Tales of the Last Century,’ Louisa became the mother of a son, in 1773. The alleged event was kept a profound secret, and the child was as secretly carried on board an _English man of war_! commanded by Commodore O’Halleran, who, if he had his rights, was not only foster-father to the mysterious infant, but also Earl of Strathgowrie! Admiral Allen, it will be remembered, was thought to be heir to the earldom of Errol. [Sidenote: ‘_RED EAGLE._’]
