Gibbs recorded "a flat scraper" from a "pocket of bedded clay" in the Fulwell Quarries. Young has not seen this object, and its whereabouts are unknown.

A socketed bronze axe was found in the River Wear at Hylton. There is no further information, and its whereabouts are unknown.

In August 1823 "...a human skull and some bones, much in decay, were dug up by the side of Fulwell-hill, near Sunderland". Sykes goes on to remind the reader that, in C9, there had been battles with the Danes here, and in C17 Civil War actions. The second grid ref includes the higher ground west of Fulwell. Miket includes this site in his Prehistoric Gazetteer without any evidence.

In 1900 or 1901 there was found "in an Ancient British grave at Fulwell" a skeleton "about four feet below the surface in a sand bed; it was covered with (limpet) shells (of which there were several hundreds)...and a large stone on the top". Also in the grave, described as a cist in the second reference in source 1, were fragments of cinerary urns. The urns, of which there is a photo, were broken by the workmen, as were the large stones which formed the cist", and the bones were covered up. As the find was apparently made by contractors for the new streets, and the grave cover was used for the foundations of the new street footpaths, it seems possible that it was not actually found in Fulwell Quarry, as Miket suggests. The above grid ref is that favoured by the Ordnance Survey.

In 1323 Robert, lord of Hylton, granted the chantry of St. Mary in the chapel of Hylton to his clerk, Robert de Chillingham. Among its endowments were 4.5 acres in the vill of Clowcroft. In 1361 Clowcroft, Grindon and Ford were held by Alexander Hilton for 1 knight's fee, value c marc. In 1431 Robert Conyers held the manor from Sir William Hilton, and in 1438, with the manors of Homyldon, Barnes and Pavyllon, Johanna Bromflete held 2 tofts and 17 acres in Clowcroft from Baron Hilton. In c. 1447 the manor was held by Sir William Bowes whose family continued to hold it from the Hiltons through the C16. The last known reference is 1608 when it was part of a grant of the manors of Hamildon and Barnes to Ralph Bowes of Barnes. There is no precise clue to its location. It was not a township but, because in grants it is often joined to Ford, Grindon, Hamilden or Barnes, it is likely to have been south of the River Wear. Dated C14th.

In 1448, in an i.p.m. of one of the Hylton family, who held the manor of Bermeston, reference was made to "the site of the mansion worth nothing". There is no further information, and no clue as to its location. Can it be equated with the hall shown on the Burleigh and Thompson map of 1737? Dated C15th.

During the Middle Ages Barmston was held by the Hylton family , and their property there included a mill, sometimes two. In 1323 there is reference to the mill of Bermeston, and in 1448 there were two water mills, "worth nothing because totally waste". There is no further information, and their location is unknown though there were, within the township, several burns running south into the Wear. Dated C14th.

During the Middle Ages Barmston was held by the Hylton family, and their property there included a park. In 1323 the chantry of St. Mary, in the chapel of Hylton, included among its endowments the honey and wax in the trees in the park of Bermeston (presumably from wild bees). And in 1448 the manor of Bermeston included a park of 90 acres, worth 4d each. There is no further information, and its location is unknown. Dated C14th.

The hall was demolished either in 1966, because subsidence had made it unsafe (1), or in 1968-70 (2). It is shown on the O.S. 1967 map. Part was "said to be C16" (2), and a rather poor drawing in (1) suggests it originally consisted of a central block with a projecting wing at each end, cf. Washington, apparently with mullioned windows. Can this be right? It has been described as "a Georgian stone-built house with bow window", and was listed II*. (1) lists various owners/occupiers, though with no evidence - William Hylton, one of the Pilgrim Fathers; in the 18th century Nicholas Lambton Esq.; and the last tenants Messrs. J. and C. Cook, metal founders. Demolished in 1966 in the expansion of Washington New Town. Despite its apparent C19 exterior, it was an old house with work from C16 onwards. Some rooms were panelled, in an early C18 style. The rich ceiling decoration was probably C19. The estate belonged to various families, the Hyltons of Hylton Castle, the Carrs of Cocken Hall, and then the Davison family. In 1856 the estate belonged to Joseph Cook, of Messrs. J and C. Cook, ironfounders, spade and shovel makers. It was still the seat of Joseph Cook in 1894. Greenwood's map of 1820 shows North Biddick as a single house surrounded by trees. The 1857 First Edition Plan shows the hall with its ornamental gardens and orchards to the north and approach drive from Biddick Lane. The second edition map 1896 shows changes to the frontage of the hall and additional new outbuildings to its north. An entrance lodge was also present by this time at the Biddick Lane end. This building is still extant. The 1929 plan shows the entrance drive realigned towards the south. This boundary retains a line of mature chestnut trees probably planted at this time.

There were three pits: Frederick (1815-1914), Victoria and Wellington (1845-1974). Owners were George Elliot, then J Johansson and Sir George Elliot, 1882 John Bowes & Partners, then Johansson, Gordon & Co Ltd, then Leversons Wallsend Collieries Ltd, 1940 Washington Coal Co Ltd and 1947 National Coal Board. O.S. maps show a large settlement, with terraces of houses round two 3-sided squares, Post Office, two chapels, a school (built 1863 for 600 children), miners' hall (substantial brick building built in 1891 at a cost of £1800, including a lecture hall, reading room, billiard room, community room and caretakers house), spoil heaps and mine buildings, all immediately east of Little Usworth, and a wagonway going ENE to join the NER Newcastle, Leamside, Ferryhill Line. There was an explosion on 5 June 1850 which killed 13 miners and another on 2 March 1885 which killed 42. There is a memorial to the victims in Holy Trinity Churchyard in Donwell. In 1890 the engine house was destroyed by fire. Whellan reports that in 1894 the colliery produced 1000 tons a day and employed 750 men and boys. In 1959 the colliery was joined to Follonsby Colliery (HER 6942) by an underground loco road. Maudlin seam abandoned 1954. Brockwell seam abandoned 1914.
