Overview
The Delaval family was an aristocratic Northumberland family whose history extended from the period following the Norman Conquest to the extinction of its male line in the early nineteenth century. The family name derived from Laval, a town in the valley of the Mayenne in north-western France. An early ancestor, Guy de la Val I, is associated with a castle at Laval during the first half of the eleventh century. After the Norman Conquest of England in 1066, members of the de la Val family established themselves in Northumberland, where they became connected with Seaton and its surrounding estates. The family’s principal seat was Seaton Delaval, near the Northumberland coast. An early fortified residence stood close to the existing Saxon church, and around 1100 Hubert de la Val rebuilt the church that later became the Church of Our Lady near Delaval Hall. The residence developed over time into a medieval tower and was subsequently enlarged during the Tudor and Jacobean periods. In the early eighteenth century, the older manor house was replaced by Seaton Delaval Hall, the final major country-house project designed by Sir John Vanbrugh. The hall became the most visible expression of the family’s wealth and status. The Delavals were active in county administration, military service and parliamentary life. Members of the family served as High Sheriff of Northumberland, represented constituencies in Parliament and acted as commissioners involved in the administration of the Anglo-Scottish border. Their regional influence was supported by landed wealth and by commercial and industrial interests. During the eighteenth century, the family was involved in the development of Seaton Sluice, a small coastal port, and in coal mining at Old Hartley. These activities connected the family’s estate management with maritime trade and the extractive economy of Northumberland. The eighteenth century was the family’s period of greatest prominence and is remembered for the unconventional lifestyles of several Delavals as well as for their patronage, theatricality and conspicuous use of Seaton Delaval Hall. Important figures included Admiral George Delaval, Captain Francis Blake Delaval, Sir Francis Blake Delaval, Lord John Hussey Delaval and Edward Hussey Delaval. Lady Rhoda Delaval Astley, a member of the same family circle, was an artist whose portraits of relatives are preserved in collections associated with Seaton Delaval Hall. The Delaval surname was reportedly lost and later re-adopted on more than one occasion during the medieval period, apparently because of the prestige attached to its Norman-French associations. The direct Delaval line ended with the death of Edward Hussey Delaval in 1814. The Seaton Delaval manor and other estates then passed to the Astley family of Melton Constable. Seaton Delaval Hall suffered a major fire in 1822. Although it was subsequently restored, the interior of the principal block was not fully reinstated. The Astley family retained the estate for many years. Edward Astley, 22nd Baron Hastings, devoted substantial effort to restoring the hall and lived there until his death in 2007. His heir, Delaval Astley, 23rd Baron Hastings, later transferred the hall to the National Trust in the face of substantial death-duty liabilities. The family’s historical legacy is therefore represented less by an operating business than by its surviving buildings, archives, portraits, estates and associations with Northumberland’s coastal, mining and maritime development.
History
The Delaval family traced its name to Laval in the former province of Maine, in present-day north-western France. Following the Norman Conquest of England, the de la Val family settled in Northumberland and became associated with Seaton. Their early residence was a fortified dwelling near a pre-existing Saxon church. Around 1100, Hubert de la Val rebuilt the church, establishing the building later known as the Church of Our Lady near Seaton Delaval Hall. The original residence appears to have developed into Seaton Tower, probably during the fourteenth century. Later owners expanded it during the Tudor and Jacobean periods, producing a large and irregular manor house. In the early eighteenth century, the family replaced this structure with the present Seaton Delaval Hall, designed by Sir John Vanbrugh. It was Vanbrugh’s third and final great mansion and became the architectural centre of the family’s influence in the region. The surname did not pass continuously through the medieval period. It disappeared from the direct line at least twice and was subsequently adopted again by lords of Seaton, presumably because the Norman-French name carried social prestige. Regardless of these genealogical interruptions, the family maintained a prominent position in Northumberland. Several members held the office of High Sheriff, served in Parliament or participated in border administration. Others pursued naval and military careers. The family’s influence reached beyond politics and estate ownership. The Delavals helped develop Seaton Sluice as a small port and were connected with coal mining at Old Hartley. These activities reflected the economic transformation of the Northumberland coast, where coal production, shipping and estate resources were closely related. The family’s eighteenth-century prosperity supported the construction and maintenance of Seaton Delaval Hall and the elaborate social life for which the later Delavals became known. Among the best-known eighteenth-century members were Admiral George Delaval, Captain Francis Blake Delaval, Sir Francis Blake Delaval, Lord John Hussey Delaval and Edward Hussey Delaval. Their reputations combined public service with colourful personal lives and, in some cases, artistic and theatrical interests. Lady Rhoda Delaval Astley produced portraits of family members, many of which remain associated with the National Trust collection at Seaton Delaval Hall. The family’s fortunes declined after their eighteenth-century peak. Edward Hussey Delaval died in 1814, bringing the direct Delaval line to an end. Ownership of Seaton Delaval and related estates passed to the Astley family of Melton Constable. A fire severely damaged Seaton Delaval Hall in 1822. The building was later restored, although the interior of its principal block remained substantially incomplete. The Astleys continued the preservation of the property. Edward Astley, 22nd Baron Hastings, spent many years restoring the hall and made it his principal home until his death in 2007. Delaval Astley, 23rd Baron Hastings, subsequently faced significant inheritance-tax obligations and sold the hall to the National Trust. The surviving estate, family papers, portraits and architectural remains now provide the principal evidence of the Delaval family’s historical importance.
