William Newton (1512–1590) built Southover Grange in 1572. He was born in 1512 in
Cheshire and was the second son of Humphrey Newton of Fulshaw and grandson of the notable Humphrey Newton (1466–1536) of Pownall His mother was Ethelred Starkey an heiress of her father Lawrence Starkey and brought into the family extensive properties in
York,
Lancaster,
Chester and
Stafford. In 1544 William and his younger brother Lawrence moved to
Lewes. He lived at
Lewes Priory in Southover which he leased from the then owner
Anne of Cleves. In about 1550 he married Jane Ernley who was the daughter and heiress of William Ernley, owner of the Manor of Eryles. The couple had one son Nicholas Newton who was born in about 1552. In 1560 William bought a property called “East Mascalls” near
Lindfield which he later gave to his son Nicholas. They had six children, two sons and daughters. Jane died in 1627 and William married Jane, the widow of John Stansfield who was the grandfather of the famous diarist
John Evelyn. The newly married Jane Newton was very fond of her grandson John Evelyn and offered to care for him so that he could go to the free-school at Southover. His father wanted him to go to Eton but John accepted his grandmother’s offer and spent most of his childhood at Southover Grange. William Newton died in 1648 and his second wife Jane died in 1650. William’s son by his first wife William Newton (1598–1658) inherited the property. He was born in 1598 in
Lewes and in 1637 he married Dorothy, daughter of Sir John Rivers 1st Baronet. He died in 1658 and his second son Apsley Newton (1639–1718) became the owner of Southover Grange. It then passed to his grandson William Newton (1691–1775) because his son had predeceased him. When he died in 1775 Southover Grange was inherited by his great nephew Colonel William Newton. William entered the military forces and in 1782 was a Major and then four years later a Lieutenant Colonel in the
10th Light Dragoons (Hussars) which were selected by the Prince of Wales (later
King George IV). William was a personal friend of the Prince of Wales who often visited him at Southover Grange. In his Will he mentions that he was given a gold watch by the Prince as a pledge of his friendship. In 1788 at the age of 44 he married Anne Elizabeth Knatchbull (1757–1837) who was the daughter of
Sir Edward Knatchbull, 7th Baronet. Her nephew
Sir Edward Knatchbull, 9th Baronet married the niece of
Jane Austen, Fanny Catherine Knight. William continued his military career after their marriage. From 1786 until 1793 he was the commander of the 10th Light Dragoons. He died in 1808 and Anne remained at Southover Grange until her death in 1837. They had no children so when she died William’s niece Elizabeth Mabbott inherited the property. Elizabeth Mabbott (1769–1859) (née Newton) was born in 1769 in
Isfield,
Sussex. She was the only child of Reverend George Newton (1729–1791) and Elizabeth Geere (1729–1811). She was an heiress from many sides of the family. Besides the Newton inheritance her cousin Thomas Holles Payne left her
Ovingdean Manor when he died in 1799 and the Geere family left her
Bevendean Estate in 1811 when her mother died. Elizabeth married William Courthorpe Mabbott (1774–1860) in 1808. He was born in 1774 in
Hampshire. His father was William Mabbott (1745–1812) of Cassington and his mother was Frances Courthorpe. At an early age he entered the 11th Hussars and in 1798 became a Lieutenant. He fought at the
Battle of Waterloo. After his father died in 1812 he inherited his estates so he retired from the army and became a country squire. He was a controversial figure as he helped to suppress the
Swing Riots during the 1830s. He also wrote many letters to the newspapers expressing his political views. Elizabeth died in 1859 and William died the following year. In 1864 the house was advertised for sale and the sale notice is shown. The property was bought in 1865 by Captain Charles Wyndham. ==Owners after 1860==
