 of the civil war, but was reinstated along with his father-in-law by the council of state in August 1653 (Cal. State Papers, Dom. 1653–4, p. 118). The son, however, appears to have held different views. At an early age he entered the navy, and attained the rank of captain. He was sworn in jurat of the royal court, 2 Feb. 1681. On the accession of James II in 1685, he presented him with a manuscript, giving an account of the Channel Islands, with suggestions for their defence. It remained among the state papers until about the close of the last century, when it was transmitted to Admiral d'Auvergne, duke of Bouillon, the then naval commander at Jersey. By his permission copies were allowed to be made. ‘If I am not mistaken,’ says Edward Durell, ‘the original is still in the governor's office’ (, Jersey, ed. Durell, 1837, p. 284). Payne (Armorial, p. 135) wrongly asserts the original to be ‘preserved at the British Museum;’ he had probably confused it with ‘a plan of the coast of the island of Jersey’ by John Dumaresq (Addit. MS. 15496, f. 14). From his letters Dumaresq seems to have been an amiable, well-informed man, who devoted most of his time to gardening, fruit, and tree culture. He was the friend and correspondent of John Evelyn (Addit. MS. 15857, ff. 225–7;, Diary, ed. 1850–2, iii. 189, 227–8). There are also a few of his letters to Christopher Lord Hatton, when governor of Jersey, in Addit. MS. 29560, ff. 108, 212, 318. Shortly before his death he imparted to Philip Falle, who was then engaged on his history of the island, ‘a set of curious observations;’ but what was still more valuable, an accurate survey of Jersey, ‘done on a large skin of vellum,’ and ‘equally calculated for a sea chart and a land map,’ which in a reduced form adorns the front of Falle's book (see Falle's prefaces to first (1694) and second (1734) editions). Dumaresq died in 1690. By license bearing date 24 June 1672 he married at the Savoy Chapel, London, Deborah, daughter of William Trumbull of Easthampstead, Berkshire (, London Marriage Licenses, ed. Foster, p. 426; pedigree of Trumbull in Genealogist, vi. 100). Mrs. Dumaresq died in 1720 at Hertford (Probate Act Book, P. C. C. 1720), and desired to be buried at Easthampstead ‘as near my dear father as may be.’ Her will of 25 Dec. 1715, with two codicils of 2 (sic) Dec. 1715, and 24 Oct. 1717, was proved at London 20 Dec. 1720 (registered in P. C. C., 252, Shaller). Dumaresq's only child, Deborah, married Philip, son of Benjamin Dumaresq, a junior scion of Dumaresq des Augrès, but she died without issue. She was the last of her family who held the seigneurie of Samarés, having conveyed it to the Seale family.

DUMBARTON, (1636?–1692). [See .]

DUMBLETON, JOHN (fl. 1340), schoolman, was doubtless a native of the village of Dumbleton in Gloucestershire. Another John of Dumbleton was a monk at Worcester shortly before, and in 1299 was appointed prior of Little Malvern (Annales Monastici, iv. 542, 548, ed. H. R. Luard, Rolls Series, 1869); but the subject of this notice, though the church of Dumbleton was closely connected with the abbey of Abingdon (see the Annales Monasterii de Abingdon, passim, ed. J. Stevenson, Rolls Ser.), did not enter the monastic life, but became a fellow of Merton College, Oxford, the statutes of which excluded all but seculars. At what date he went to Oxford is unknown. The biographers say that he flourished in 1320, but such dates are notoriously in most cases conjectural. The college accounts testify to the existence of a Thomas of Dumbleton in 1324, but do not mention John until 1331. It is possible that ‘Thomas’ is a mistake for ‘John.’ On 27 Sept. 1332 he was presented to the living of Rotherfield Peppard, near Henley, in the archdeaconry of Oxford, which, however, he resigned in 1334. In 1338–9 we find him attending college meetings at Merton (, History of Agriculture and Prices, ii. 670–4, 1866). In February 1340–1 he was named one of the first fellows of Queen's College in the original statutes (p. 7, ed. 1853); but in 1344 and 1349 his name reappears in the books of Merton College. Whether at Queen's or at Merton, he may be presumed to have remained at Oxford for the rest of his life, and there to have written the works which won him a distinguished scholastic reputation, evidence of which may be found in the number of copies of his writings still preserved in the college libraries, as well as in the curious fact that the fame of John Chilmark [q. v.], which was not inconsiderable in the latter part of the fourteenth century, rested to a great extent upon a treatise, ‘De Actione Elementorum,’ which is in fact, according to the statement of its very title (Bodleian Library, Digby MS. lxxvii. f. 153 b), nothing but a ‘compendium’ derived from the fourth book of Dumbleton's ‘Summa Logicæ.’

Dumbleton wrote: 1. ‘Summa Logicæ et Naturalis Philosophiæ’ (Merton College, cod.
