A typical Georgian country family

This seems to be to be a typical development through the 18th and 19th centuries.

"John Spencer
Born 1718, died 1775. John's ancestors had accumulated wealth through the early iron industry. Coal pits took on more importance during their tenure. John was a huntsman, a bold rider, a hard drinker with a violent temper and speech, but open and warm hearted with good manners, a paternalistic approach. He was scholarly and possessed a large library. He was never interested in politics but became a racehorse owner and ran cockfights on Sunday in Cawthorne Park. However he attended the local All Saints Church regularly. Parson Phipps at this tme lived at Banks Hall, a batchelor for most of his life (An "old parochial squire") with no male issue.
John Spencer introduced about 100 deer into the park between 1760 and 1766, they were purchased in February. 1762. 18, pl93 The deer 'dissipated 'during WW2. By 1807 the Hall was basically as it is today.

Walter Spencer-Stanhope
Born 4th Feb 1749 died 4th. April 1821. He inherited Cannon Hall from his uncle, John Spencer in 1775. Walter changed his name from Stanhope to Spencer-Stanhope (18, p2) A politician, educated at Bradford Grammar School, University College, Oxford, Law studies at Miiddle Temple member for Carlisle (first of four constituencies). A close supporter of William Pitt the Younger and William Wilberforce (Yorkshire anti-slavery campaigner).William Wilberforce was a frequent visitor to Cannon Hall.

Walter had income from estates, iron furnaces and coal mines. A bloomery had operated at Cinder Hill and there still are numerous "Smithy Fields"12, p51 to the north (see Ordnance Survey maps)
In the l650's the Spencers' had manufactured iron at Bamby Furnaces, Wortley Forges, Bank Furnace (Thornhlll Parish) and Kirkstall Iron Works near Leeds. Timber was taken from the surrounding woodlands for this purpose.l2, p62 Even back in 1352 there was a contract to supply wood and iron for the "iron blomes at Kirkstell near Otley".12, p51
By the 1750's pit coal was being used in the smelting of iron, and after1744 the occupation of "collier" was listed more frequently in the Parish Register.12, p62

In 1783 he married Winifred Pulleine (she was an only child) this gave him more property and wealth in North Yorkshire such as Carlton Hall, Nr Richmond and in Northumberland. They were blessed with a happy marriage producing 15 children.
Walter was a humanitarian (eg pre 1775 he had all the Horsforth Estate tenants vaccinated against smallpox). He became a religious humanitarian after meeting William Wilberforce.18, p4
In 1787 Walter began the practice of delivering the Sunday evening sermon.18, p4 He worked against the cruelty to animals in sport, e.g. in July 1794 he had a bull-baiter shoot his own bull; bull Baiting was made illegal by 1835.18, p4
By 1799 the Barnsley Canal had been opened with a branch line to Barnby (Cawthorne) Basin, this allowed the collieries at Silkstone and Barnby Furnace to increase their output. By the early 1800's the largest output had been achieved at Norcroft and Bamby Furnace.12, p62

Cliffe hill was the main road to Cannon Hall in the late1700's to the early 1800's. It is now little used, the main entrance being more directly in front of Cannon Hall itself.
In 1805 Walter Spencer-Stanhope commanded 600 Staincross Volunteers, a false alarm was raised (instead of a warning beacon, a brick kiln had been lit near Pontefract Beacon) The Volunteers walked to Hemsworth on the way to Pontefract, when informed by a horserider with a letter.
