She also bequesthed a guilt cup and cover, which had belonged to the Queen, and which she had purchased, to her good mistress the Countess Dowager of Derby and an emerald ring to her dau. Lady Henrietta, and rings to a number of their servants, which seems to intimate that she had been in the service of that family.

She married William George Richard Stanley, 9th Earl of Derby, son of Charles Stanley, 8th Earl of Derby and Dorothea Helena van den Kerchhove, on 10 July 1673.2 She died on 5 July 1717.

 Capt. George Slaughter, born in Gloucestershire,  had been a cornet to the first Duke of Ormond: he directed these facts to be stated on his gravestone, in his will dated 19 Jan. 1693-4. In a later will, dated 24 Dec. 1695, he called himself of Shanbally, co. Tipperary, Ireland, Gent. He bequeathed his estate in Shanbally to his nephew George-Slaughter Batty, son of his nephew Thomas Batty, Gent., on condition that he used the surname of Slaughter only ; and other considerable legacies to other children of said Thomas Batty (who had apparently married his niece), but the dau. Elizabeth Batty was to have only five shillings, instead of £400, if she married any “Irish papist." To his sister Amy (afterwards Amy Lawrence) he left an annuity of £20 for life, and other legacies to the son of his niece Thawyts, his cousin Matthews, and his nephew John Haubury and his wife. The will was proved, 2 Mch. 1695-6. by his sister Mary Pomeroy (see her burial 10 Oct. 1707), to whom he left £1,200. He died 1 Jan. 1696/7.
