_Sewell Family_ (Vol. viii., p. 521.).--Your correspondent D. N. states, that "nothing farther is known of the family of Lieut.-Col. Sewell, who died in 1803, than that he had a son Thos. Bailey Heath Sewell, Cornet in 32nd Light Dragoons, and Lieutenant 4th Dragoon Guards." Had he referred to Lodge's _Peerage_, he would have found that the Honorable Harriet Beresford, fourth daughter of the Most Rev. Wm. Beresford, Lord Archbishop of Tuam, and first Baron Decies, married Jan. 25, 1796, Thos. Henry Bermingham (not Bailey) Daly Sewell, Esq.; and died June 11, 1834, having had three children, viz.: 1. Thomas, formerly Page of Honour to the Lord Lieutenant of Ireland, _circa_ 1829, afterwards a pensioner of Trin. Coll. Dublin, and subsequently Lieutenant 13th Light Infantry; who died at Landour, Bengal, Aug. 1, 1836. 2. Isabella, who married her cousin Major Marcus Beresford, in October, 1828; and died in 1836. 3. Louisa, married to the Hon. Sir W. E. Leeson, and died in 1849 or 1850. Will D. N. favour me with the dates of the birth and death of the late unfortunate, and, as I believe, ill-used Lieut.-General John Whitelocke, whom he mentions, with the localities where the birth and death occurred? G. L. S. [We have submitted our correspondent's communication to D. N., who has kindly forwarded the following reply: "My communication (Vol. viii., p. 521.) I was aware was far from a perfect pedigree of the Sewell family, and my object was to give such notices as might form an outline to be filled up by some one more competently informed. Your correspondent G. L. S. has very well supplied the _cætera desunt_, where my information terminated with the appointment of Cornet Sewell to a Lieutenancy in the 4th (Royal Irish) Dragoon Guards. In the London Gazette 13789, June 23, 1795, he is inserted as 'Mr. Bermingham Daly Henry Sewell' to be a cornet in the 32nd Light Dragoons; and as in filling up commissions much accuracy is always considered very essential, I am disposed to regard those Christian names as correct. "There was a Rev. George Sewell, Rector of Byfleet, Surrey, Was he a brother of Lieut.-Col. Sewell of the Surrey Light Dragoons? "Did the Right Hon. Sir Thomas Sewell marry a second wife? For I find, in _The Globe_ of October 9, 1820: 'Died, Saturday, Sept. 16, at Twyford Lodge, Maresfield, Sussex, in her seventy-eighth year, Lady Sewell, widow of the late Right Hon. Sir Thomas Sewell, Master of the Rolls and Privy Councillor, &c.' Now, in Manning's _Surrey_, vol. iii. p. 201., it is stated that Lieut.-Col. Sewell died in 1803, in his fifty-eighth year, which would render it impossible for him to be the son of the above-named Lady Sewell. In Horsfield's _Sussex_, 4to., 1835, vol. i. p. 375., I find a William Luther Sewell, Esq., who most probably was connected by the second marriage, residing at the above Twyford Lodge.
