Andrew followed his father’s profession of Writer, and when Prince Charles came to Edinburgh in 1745 he was, on the recommendation of his cousin Sir Alex. Dick of Prestonfield, appointed private secretary to the Prince, and accompanied him throughout the campaign. After Culloden he was attainted. He concealed himself for some weeks in Edinburgh, escaped to London, and thence to Rouen. Here at first he suffered great privation, but succeeded in obtaining a French pension of 600 livres, which relieved his immediate wants. In 1749 he went to Rome, and in the following year he was appointed Assistant Secretary to the Old Chevalier. On the death of James Edgar, in 1762, he succeeded him as Jacobite Secretary of State. The Old Chevalier died in 1766, and Lumisden was for a time continued in his office by Charles. The great object of Charles’s policy was to be acknowledged by the Pope as King of Great Britain, a title which Clement XIII. refused him in spite of a powerful appeal by Cardinal Henry, Duke of York, to his Holiness.[105] Charles, smarting under the indignity, became intensely irritable, and gave himself up more and more to self-indulgence. In December 1768 Lumisden, along with two other Scottish officials, was summarily dismissed for refusing to accompany his royal master to an oratorio when that master was intoxicated.[106] Leaving Rome, he settled in Paris, where he moved in the highest literary and artistic circles. In 1773 he was allowed to return to Great Britain, and five years later he received a full pardon. Lumisden, who was never married, continued to spend much of his time in Paris, accounted ‘a man of the finest taste and learning,’ living the life of a dilettante, and paying frequent visits to London and Edinburgh. There is a pleasant anecdote told of him at this time, which reflects the kindly feeling borne by King George III. to irreconcilable Jacobites. It is very similar to the well-known story of King George’s message to Laurence Oliphant of Gask, told by Sir Walter Scott in the Introduction to _Redgauntlet_. It must be remembered that to their dying day both the laird of Gask and Andrew Lumisden never referred to King George except as the Elector of Hanover. The story of Lumisden is told in a family paper[107] by his great-niece Mrs. Mure (_née_ Louisa Strange), and may be given in that lady’s own words.
