Lady Giffard was Sir William Temple's sister. She was twelve years younger than Dorothy. After her marriage and almost immediate widowhood, in 1661, she made her home with the Temples. Her _Life and Correspondence_ has been published by Mrs. Longe as a sequel to the _Letters of Dorothy Osborne_. The volume contains letters from Lady Chesterfield, from Lady Sunderland ("Saccharissa"), and others, to Lady Giffard. The letters by Lady Giffard are few in number and are all written to her niece Lady Berkeley, later Lady Portland, and belong in the years 1697-1722. These letters have none of the sparkle and humor and literary charm of Dorothy's. But we get indications that Lady Giffard was a woman of intellectual interests. We find her reading Turkish history daytimes with recourse to Virgil, "as less exacting," for evenings. She knew Spanish and French, and one of the specific items in her will is a bequest of the books she had collected in these two languages. [Sidenote: Sarah Byng, Mrs. Osborne (1693-1775)] A third series of letters, published under the title _Political and Social Letters of a Lady of the Eighteenth Century_, though belonging later in the century, may be brought in here because they carry on the series of Osborne letters. Sarah Byng, the daughter of Admiral Byng, Viscount Torrington, married, in 1710, John Osborne of Chicksands Priory, the old home of Dorothy and the place from which she wrote most of her letters. Mr. John Osborne was Dorothy's grand-nephew. He died in 1719 and his father in 1720, leaving to Sarah Osborne an infant son, Danvers, the heir to the title and a heavily burdened estate. Her letters fall in several series, the first set from 1721 to 1739 being to her brother George on business matters concerning the property. Most interesting are the letters to Danvers from 1733 to 1751. When he came of age in 1736 she was able to turn over to him an unincumbered estate, and on his marriage in 1740 she superintended the establishment of the new household at Chicksands. A third set of letters has to do with the sentence and execution of her brother Admiral Byng, in 1757. Through the death of the wife of Danvers in 1743 and the death of Danvers in 1750 Mrs. Osborne was left with two grandsons to bring up, and her last letters are to John, one of these grandsons, who was traveling in Holland.
