Evelyn's Diary. 15 Nov 1681. I dined with the Earl of Essex (age 49) who, after dinner in his study, where we were alone, related to me how much he had been scandalized and injured in the report of his being privy to the marriage of his [her aunt] Lady's (age 45) niece (age 14), the rich young widow of the late [her former husband] Lord Ogle, sole daughter of the [her grandfather] Earl of Northumberland; showing me a letter of [her husband] Mr. Thynn's (age 33), excusing himself for not communicating his marriage to his Lordship (age 49). He acquainted me also with the whole story of that unfortunate lady being betrayed by her [her grandmother] grandmother, the Countess of Northumberland (age 58), and Colonel Bret, for money; and that though, upon the importunity of the Duke of Monmouth (age 32), he had delivered to the grandmother a particular of the jointure which Mr. Thynn (age 33) pretended he would settle on the lady, yet he totally discouraged the proceeding as by no means a competent match for one that both by birth and fortune might have pretended to the greatest prince in Christendom; that he also proposed the Earl of Kingston (age 21), or the Lord Cranburn, but was by no means for Mr. Thynn (age 33).
On 15 Nov 1681 Thomas "Tom of Ten Thousand" Thynne (age 33) and Elizabeth Percy Duchess Somerset (age 14) were married. She the daughter of Josceline Percy 11th Earl of Northumberland and Elizabeth Wriothesley Countess Northumberland (age 35).
Evelyn's Diary. 14 Jan 1682. Dined at the Bishop of Rochester's (age 57), at the Abbey [Map], it being his marriage day, after twenty-four years. He related to me how he had been treated by Sir William Temple, foreseeing that he might be a delegate in the concern of my Baroness Ogle (age 14) now likely come in controversy upon her marriage with [her husband] Mr. Thynn (age 34); also how earnestly the late Earl of Danby (age 49) [NOTE. The word 'late' suggest the Earl being dead but may refer to his downfall around 1678], Lord Treasurer, sought his friendship, and what plain and sincere advice he gave him from time to time about his miscarriages and partialities; particularly his outing Sir John Duncomb (age 60) from being Chancellor of the Exchequer, and Sir Stephen Fox (age 54), above all, from being Paymaster of the Army. The Treasurer's (age 49) excuse and reason was, that Fox's (age 54) credit was so over great with the bankers and monied men, that he could procure none but by his means, "for that reason", replied the Bishop (age 57), "I would have made him my friend, Sir Stephen (age 54) being a person both honest and of credit". He told him likewise of his stateliness and difficulty of access, and several other miscarriages, and which indeed made him hated.
On 12 Feb 1682 [her husband] Thomas "Tom of Ten Thousand" Thynne (age 34) was shot and killed while riding in his coach along Pall Mall [Map], by three men, Christopher Vratz, John Stern and Charles George Borosky who were believed to be acting for her lover the Swedish Count Karl Johann von Königsmark (age 22). He was buried at Westminster Abbey [Map].
Evelyn's Diary. 10 Mar 1682. This day was executed Colonel Vrats, and some of his accomplices, for the execrable murder of [her former husband] Mr. Thynn (deceased), set on by the principal Koningsmark (age 22). He went to execution like an undaunted hero, as one that had done a friendly office for that base coward, Count Koningsmark (age 22), who had hopes to marry his widow, the rich Baroness Ogle (age 15), and was acquitted by a corrupt jury, and so got away. Vrats told a friend of mine who accompanied him to the gallows, and gave him some advice that he did not value dying of a rush, and hoped and believed God would deal with him like a gentleman. Never man went, so unconcerned for his sad fate.
