      The Hon. Mrs. Boscawen to Mrs. Delany.
      Audley Street, 5th Dec., 1785.
      . . . I have no news to tell you but "of offence and trouble," that Lady Mary Cornwallis, a very young lady indeed, is gone off to Scotland with a Mr. Singleton, of the Guards, a younger brother. At least, so I heard last night, and this morning I read that the Countess Dowager of Cornwallis is dead, as if she were spared the grief of seeing such an enormity in her family, for I can hardly give it a gentler name -- as the young lady is not yet of an age even to be presented to Her Majesty, has had the boldness to commit herself for so many hundred miles, to the care of a young man with whom she can have had but a slight acquaintance; she took no female attendant or cloathes. It must be a great trouble to Mrs. Cornwallis, and a most ungrateful return for all her care and kindness; it was, however, lucky that she did not run from her, but from her father's house in Suffolk, where she was under the care of his sister, Lady Betty Southwell, and she took the opportunity of his lordship's being absent attending upon his dying mother. It seems Captain Singleton's parents are very worthy people, and have a very large estate (in Ireland), but they have an elder son, so the appointments of this younger one are probably very inadequate to his own expenses, as he has the honour (et le malheur) to belong to the Prince of Wales's sett; and is not for that the better qualify'd to marry and settle.

      --- "Derby Mercury" 15 Dec 1785, page 2:
      London, (Monday) Dec. 19.
      Thursday Morning Capt. Singleton, of the Guards, and Lady Mary Cornwallis, Daughter of Lord Cornwallis, arrived in Town from a matrimonial Trip to Scotland.

      --- "The Gentleman's Magazine" Vol. 203, July 1857, page 101:
      May 26. At Curzon-st., aged 87, Lady Mary Singleton, widow of Mark Singleton, esq., and dau. of the first Marquis Cornwallis.

      --- "Morning Post" 29 May 1857, page 5:
      Death of Lady Mary Singleton.-- We have to record the demise, after a protracted illness, of Lady Mary Singleton, who died at her residence in Curzon-street, Mayfair, on Tuesday. The deceased lady was only suviving daughter of Charles, first Marquis Cornwallis, the celebrated general and statesman. Her ladyship was born on the 28th of June, 1769, and was consequently within a few weeks of completing her 88th year. She married in Nov., 1785, Mr. Mark Singleton, a wealthy commoner, who died in 1840. The families of the Earl of St. Germans, Mr. and Lady Mary Ross, Lord Braybrooke, the Ladies Cornwallis, &c., are placed in mourning by the demise of her ladyship.

      --- "Edinburgh Evening Courant" 09 Jun 1857, page 2:
      Died, at No. 37 Curzon Street, London, on the 26th May, the Right Hon. Lady Mary Singleton, widow of Mark Singleton, Esq., and only daughter of the first Marquess Cornwallis.
