He departed this life in the 49 year of his age And was buried in great state out of the Duke of Buckingham's House Many illustrious persons of all degrees attending his funeral. August 3d. 1667. COUNT KÖNIGSMARK AND THE DUCHESS OF SOMERSET. Several notices of Count Königsmark have lately appeared in "N. & Q.," Walpole's mistake having occasioned a question by MR. MARKLAND respecting his identity. There can, however, be no doubt that the person who was tried for being accessory to the assassination of Mr. Thynne in 1681-2, and whose trial is reported at length in the 9th volume of Howell's _State Trials_, p. 1., was Charles John Count Königsmark, as stated by MR. BRUCE in Vol. v., p. 115. of "N. & Q.," and whose biography and genealogy are more fully given by J. R. J. in p. 183. of the same volume. In the Note on this subject by J. R. J. it is stated that "the most mysterious episode in the life of this Count Königsmark was brought on by his sueing for England's richest and highest heiress, Elizabeth, daughter of Josceline, second Earl of Northumberland." This is perfectly true; but the personal history of this lady, her connexion with Königsmark, her imputed privity to the murder of Mr. Thynne, and the savage allusion to these circumstances by Swift thirty years afterwards, deserve a more particular notice. Elizabeth, Baroness Percy, was daughter and heiress of Josceline, Earl of Northumberland, who died in 1670. According to Collins (_Peerage_, vol. iv. p. 185.) she was four years old at the time of her father's death; so that she was born in 1666. In 1679 she was married to Henry Cavendish, Earl of Ogle, who was only son and heir of the Duke of Newcastle, and who died in 1680, before either party were of puberty to consummate the marriage. In 1681 the Lady Ogle was married to Thomas Thynne, of Longleat, in the county of Wilts, Esquire,--a gentleman of great wealth, a friend of the Duke of Monmouth, and the Issachar of Dryden's "Absalom and Achitophel." Sir John Reresby, in his _Memoirs_, p. 135., says "The lady, repenting of the match, fled from her husband into Holland before they were bedded." Whether this elopement had any relation to Königsmark does not appear: but a few months afterwards, namely, in February 1681-2, Mr. Thynne was assassinated in the Haymarket by foreigners, who were devoted friends of the Count, and who apparently acted under his direction, or, at all events, with his acquiescence. The Count was at that time a mere youth, and having been in London a few months before Lady Ogle's marriage with Mr. Thynne, had then paid his addresses to her. He returned into England about ten days before the murder, and was in London at the time it was committed. In endeavouring to escape beyond sea the day afterwards, he was taken in disguise at Gravesend, brought to Westminster, and examined before King and Council. Sir John Reresby says, "I was present upon this occasion, and observed
