MARLBOROUGH, a borough and market-town, having separate jurisdiction, though locally in the hundred of Selkley, county of WILTS, 27 miles (N. by E.) from Salisbury, and 75 (W. by S.) from London, and containing 3038 inhabitants. The name, anciently written Marleberg, or Marlbridge, is supposed to be derived from the marl, or chalk, hills by which the town is surrounded. Camden supposed this to have been the Cunetio of Antoninus, but more recent researches induced Sir R. C. Hoare, Bart, to place that station at Folly Farm, about a mile and a half eastward from the town, where that celebrated antiquary discovered a tesselated pavement, and other relics of a Roman settlement. At the time of the Norman survey Marlborough had a church, and was held in royal demesne, soon after which period a castle was erected, which seems to have been the cause of the subsequent enlargement of the town. In the time of Richard I., and during his Imprisonment in Austria, his brother John took possession of this fortress but on Richard's return from captivity, he seized it, with all the other possessions belonging to his brother, and on their reconciliation he still retained the castle of Marlborough in his own possession. During the subsequent reign, King John occasionally kept his court here; and in the civil war of this period, Marlborough was possessed alternately by the king and the barons: it seems, indeed, to have been the occasional residence of subsequent sovereigns till the time of Henry VII., and to have formed part of the dowries of several queens. The assizes were held here from the time of Henry III. to that of Charles I.; and in the 52nd of Henry III. that parliament assembled here by which were enacted the laws relative to the police of the kingdom, and to the administration of justice, commonly called the " Statutes of Marlebridge." The castle, borough, &c., were granted by Henry VIII. to Edward, Duke of Somerset, and became forfeited to the crown on the attainder of that nobleman, in the reign of Edward VI., but were subsequently restored to the Somerset family, and have now descended, by intermarriage, to the Marquis of Ailesbury. Even in Camden's time, a few fragments only of the castle were remaining; a large house, now the Castle Inn, which occupies its site, is said to have been commenced by the first duke of Somerset of the Seymour family, and was improved by the Earl of Hertford, in the early part of the eighteenth century: the old keep has been converted into a spiral walk, in the grotto of which, Mrs. Rowe wrote the most celebrated of her works, "Friendship in Death; " and here also Thompson is said to have composed a great part of his " Seasons," when on a visit to the Earl of Hertford, one of the most distinguished patrons of literature of that age. In the civil war between Charles I. and the parliament, the latter had a garrison here under the Earl of Essex; bxit the royal army, commanded by Lieut. Gen. Wilmot, marching hither from Oxford, in December 1642, captured above one thousand prisoners, besides large stores of arms and ammunition, with all which they returned in safety to that city. Marlborough having suffered repeatedly from fire prior to the year 1690, an act of parliament was passed in that year to prohibit the use of thatch as a covering for houses and other buildings within the borough. The town is delightfully situated on the banks of the Rennet, on the northern verge of the Forest of Savernake, and on the north of it are the open downs; it consists principally of one long street, running from east to west, which is paved, and lighted with gas; the older houses are constructed of wood, and ornamented in front with curious carved work,- the more modern are of stone and brick. On the north side of the principal street is a piazza projecting in front of the houses, serving for a promenade in wet weather; and at its eastern extremity is a market-house, erected on the site of a former one, by the corporation, in 1790: the upper story is divided into a council-chamber, an assembly-room, and a court-room. The inhabitants are well supplied with water. The manufactures are inconsiderable: the trade is principally in corn, coal, and malt, and considerable advantages arise from the situation of the town on a great thoroughfare. The Kennet and Avon canal passes within five miles of the town, and in consequence of its not passing through it, the inhabitants' have the privilege of a draw-back upon the tonnage of goods. The market days are Wednesday and Saturday; the former market has much declined, being now only for vegetables; the latter is considerable, and has long been celebrated for its extensive supply of grain, cheese, butchers' meat, &c.: fairs are held July llth, for horses and wool; August 22nd, for lambs, horses, and cows; and November 23rd, for sheep, horses, and cows. Marlborough is a borough by prescription, and in a charter granted by Elizabeth, after referring to numerous preceding charters, the corporation is designated tinder the style of "The Mayor and Burgesses;" they are self-elected, and the present number is thirteen. The mayor (who is also coroner, clerk of the market, and escheator) and two of the burgesses are justices of the peace, and, with a town clerk, a chamberlain, two bailiffs, or Serjeants at mace, and two high constables, are chosen annually by the corporation: the mayor and justices hold quarter sessions for the .borough. The county bridewell and house of correction was erected in 1787: it comprises four day-rooms and airing-yards, and is chiefly occupied by prisoners previously to trial. Courts leet are held by the corporation, at the Lent and Michaelmas sessions, at which five constables (formerly called aldermen) are appointed, one for each ward; and a court, called the King's court, for the recovery of debts to any amount, is held every three weeks, under the charter of the 6th of John. The privilege of sending members to parliament has been exercised ever since the 23rd of Edward I., and the right of election is in the mayor and burgesses: the mayor is the returning officer: the predominant influence is possessed by the Marquis of Ailesbury. In the election of 1826 an effort was made to throw open the borough, and the subject was referred to a committee appointed by the House of Commons, who decided that the members returned by the corporation were duly elected; another attempt has recently been made, two members having been nominated by the opposing party in the election of 1830, and who have expressed their intention of trying the question a second time. Marlborough comprises the two parishes of St. Mary the Virgin and St. Peter and St. Paul, within the peculiar jurisdiction of the Consistorial Episcopal Court of Salisbury: they are divided into five wards, viz., the Green ward and Marsh ward, in St. Mary's parish; the High ward and Bailey ward, in the parish of St. Peter and St. Paul; and Kingsbury ward, in both parishes. The living of St. Mary's is a discharged vicarage, rated in the king's books at £10. 9 4., endowed with £400 private benefaction, £200 royal bounty, and £500 parliamentary grant, and in the patronage of the Dean of Salisbury; the church, a neat edifice of brick, with an ancient stone tower, beneath which is a Norman doorway, sustained considerable damage during the civil war, in 1641. The living of the parish of St. Peter and St. Paul is a discharged rectory, rated in the king's books at £12, endowed with £400 private benefaction, £200 royal bounty, and £300 parliamentary grant, and in the patronage of the Bishop of Salisbury; the church, which stands at the western extremity of the main street, has a lofty square tower with battlements and pinnacles; the nave is supported by light pillars. There are places of worship for Huntmgtonians, Independents, and Wesleyan Methodists. The free grammar school was founded and endowed with the revenue of the dissolved hospital of St. John, by grant of Edward VI. to the mayor and burgesses who were also empowered to make rules for its government: the nomination of the schoolmaster, originally given to the Duke of Somerset, is now exercised by the Marquis of Ailesbury; the income is from £200 to £300 per annum; the children of parents who have resided seven years in the town are alone eligible according to the rules, and the number of scholars on the foundation is in general about twenty. The scholars share, alternately with those of the free schools of Manchester and Hereford, in sixteen exhibitions at Brasenose College, Oxford, and sixteen scholarships at St. John's College, Cambridge, founded by Sarah, Duchess of Somerset, in 1679; and Mrs. Brown bequeathed a rent-charge of £5 for any poor scholar from this school to the University of Oxford. A National school is supported by voluntary contributions: the school-rooms were erected at the expense of the late Earl of Ailesbury. An almshouse was formerly supported from the funds of the corporation, to which several donations and bequests were made for its support in the reign of Charles II., when it was rebuilt at the expense of that body, but, in 17'25, they conveyed it to the officers of St. Mary's parish, by whom it is at present used as a workhouse. Northward from the town is a common, on which each householder has a right to turn two milch cows; and eastward of it is a close, of about eighty acres of arable ground, of which a certain portion is granted to each member of the corporate body during his own life and the widowhood of his wife, on the payment of a sum by way of fine, and a fixed rent; the cows of the commoners are depastured on the eighty acres after the harvest; and the inhabitants have an ancient privilege of turning two horses, from Old May-day to Old Martinmas-day, into the adjacent Forest of Savernake. The monastic institutions here were, a Gilbertine priory, dedicated to St. Margaret, founded in the reign of John, the revenue of which, at the dissolution, was £38.19.2.- a convent of White friars, founded in 1316 by the merchants of this town; St. John's hospital, founded in the reign of Henry II.; and St. Thomas' in that of Henry III., and annexed to the priory of St. Margaret in the reigii of Richard II. A chapel and other portions of the priory were standing a few years since. Among the distinguished natives of this town' the following may be specified; Henry of Marlborough, an English historian of the fourteenth century; Sir Michael Foster, an eminent lawyer, and one of the judges of the Court of King's Bench, born in 1689; Walter Harte, poet and historian, who died in 1773; Dr. Henry Sacheverell, of political celebrity, born in 1672, during the incumbency of his father in. the parish of St. Peter,and St. Paul; and John Hughes, a poet, and one of the writers in the Spectator, born in 1677. Marlborough confers the title of duke on the family of Spencer Churchill.
