LATHOM, a township in the parish of ORMSKIRK, hundred of WEST-DERBY, county palatine of LANCASTER, 3 miles (N. E. by E.) from Ormskirk, containing 2997 inhabitants. The free grammar school at Newburgh, in this township, was erected, in 1714, by the Rev. Thomas Crane, who endowed it with an estate at Dalton, to which Richard Okell, the schoolmaster, in 1761, added another, producing, together with an additional bequest of about £ 9 per annum, by Jonathan Lucas, in 1793, a total income of £ 52 per annum: there are one hundred scholars, of which number, forty poor children of Latham and Newburgh are instructed gratuitously. At Latham park is an ancient almshouse consisting of several tenements, with a chapel. There is a domestic chapel connected with the mansion of Lord Skelmersdale, by whom the officiating minister is appointed; his lordship has lately ornamented the chapel, at an expense of £1200, and has likewise erected a school-room, in which the children are educated at his own charge. Lathom house, once "the chief seat of the Stanleys," was originally built by the De Lathoms; during the great civil war it sustained repeated sieges from the parliamentary forces, its owner, the Earl of Derby, being one of the most staunch supporters of the royal cause. On the 28th of February, 1644, it was besieged by General Sir Thomas Fairfax, with a force of three thousand troops, but was most gallantly defended by the Countess of Derby, with only a small band of three hundred men, who, iu several destructive sallies, slew five hundred of the enemy, wounded one hundred and forty, and repeatedly destroyed their works: on the 26th of May, the assailants were obliged to raise the siege, on the arrival of the royalists under Prince Rupert. In the following year it was again besieged, by General Egerton, at the head of four thousand men, to whom, after an obstinate defence, it was surrendered, for want of ammunition, when it was plundered and the fortifications destroyed: the fine seat of the Wilbraham family now stands on its site. A market and a fair, to be held,at this place, were granted to Robert de Lathbm, in the 32nd of Edward I. Here is a saline chalybeate spring, which also contains some portion of natron.
