In 1313, Nicholas de Hastings, on the Inquisition post mortem of Robert de Clifford, held this manor, and Nateby, by homage and fealty, and 27s. 2d. cornage. The wardship whereof, when it should occur, was estimated at £40. In 1350, Ralph de Hastings held it in like manner, and in 1423 it was in the hands of Richard de Hastings by like cornage. In 1453 by a feodary it appears that Edward Hastings held Crosby by cornage of 13s. 7d. subject also to wardship, marriage, relief, and suit to the county court; and about the same time Lancelot Threlkeld seems to have held the same of the said Edward. From this time there are no more of the name of Hastings in connection with Crosby. The only relic of this family is a slab which was found in the churchyard, having an incised cross and shield upon it, bearing the arms of the Hastings; which differ from those of the Threlkelds only in colour. The principal residence of the Threlkeld family was at Threlkeld in Cumberland; but they had large possessions at Crosby long previous to this time, for in 1304 and 1320 Henry Threlkeld had a grant of free warren in Yanwath, Crosby, Tibbay, &c., and in 1404 occurs the name of William Threlkeld, Knight, of Crosby. Sir Lancelot Threlkeld, Knight, was the son of Sir Lancelot Threlkeld, by Margaret, daughter and heiress of Henry Bromflatt, Lord Vescy, and widow of John de Clifford. He was wont to say he had three noble houses; one at Crosby Ravensworth for pleasure, where he had a park full of deer; one at Yanwath for comfort and warmth, wherein to reside in winter; and one at Threlkeld, well stocked with tenants, to go with him to the wars. This Sir Lancelot has been buried in Crosby Church beneath the large tomb in the chapel belonging to Crosby Hall. The tomb is solid mason-work, ornamented with flutings on all sides, and on the south side with three blank shields, on which the armorial bearings would probably be painted. On the top is an immense polished limestone slab, without any ornament whatever; but on which it may have been the intention to have afterwards placed an effigy. Above this as a canopy is a low, flat arch, richly moulded, and on the north side enriched at each end with the arms of the Threlkelds, and in the centre the same impaling that of Bromflatt. At a later period the vault beneath was appropriated for the occupation of Robert Lowther, Esq., of Maulds Meaburn Hall, and probably at the same time the tombs underwent some alteration.
