Arthur St Leger, 1st Viscount Doneraile
Arthur St Leger, 1st Viscount Doneraile (died 7 July 1727) was an Anglo-Irish politician and peer.
St Leger was the son of John St. Leger and his first wife Lady Mary Chichester, the daughter of Arthur Chichester, 1st Earl of Donegall and his first wife Dorcas Hill.
He was a descendant of Sir Anthony St Leger.
Sir John St Leger, Baron of the Court of Exchequer (Ireland), was his half-brother, the son of his father's second marriage to Aphra Harflete, an heiress from Ash in Kent.
John, who was not highly regarded as a lawyer, was said to have owed his success largely to his brother's support, and the two were close throughout their lives.
St Leger represented Doneraile in the Irish House of Commons from 1692 to 1693.
On 23 June 1703 he was raised to the Peerage of Ireland as Viscount Doneraile and Baron Kilmayden.
In 1715, he was invested as a member of the Privy Council of Ireland.
His most noted contribution to public life was during the debate in the Irish House of Lords on the much-debated case of "Sherlock v Annesley" in 1719.
The Barons of the Exchqeuer, including Doneraile's brother John, had given effect to a decree of the British House of Lords, ignoring a contrary decree of the Irish House.
The Irish peers, infuriated by this challenge to their authority, summoned the judges to appear before them and after a short, ill-tempered hearing committed them to prison for three months.
The only peers to vote against committing the judges were Doneraile and the Lord Chancellor of Ireland, Lord Midleton.
While the Lord Chancellor was concerned at the political implications of the Lords' conduct, warning rightly that the House was at risk of losing its judicial powers altogether, Doneraile seems to have been moved by simple family loyalty, as he and his brother were close.
He married Elizabeth Hayes, the daughter of John Hayes, on 24 June 1690.
Together they had four children.
Both of his two surviving sons would, in turn, succeed to his titles.

Anthony St Leger (British Army officer)
Major-General Anthony St Leger (1731/32 – 19 April 1786) was a successful soldier, a Member of Parliament for Grimsby, and the founder of the St. Leger Stakes horse race.
Born in February 1731 at Grangemellon, County Kildare, Ireland, he was the fourth son of Sir John St Leger (1674–1743), who was a judge of the Court of Exchequer (Ireland), and his second wife Lavinia, daughter of Kingsmill Pennefather of Cashel, County Tipperary.
He was educated at Eton College.
He attended Peterhouse, Cambridge, before embarking on a career in the army.
His brother Barry St. Leger was also a distinguished army officer.
They belonged to the junior branch of a long established landowning family from County Cork: the head of the senior branch was Viscount Doneraile.
In 1761, St Leger married a Yorkshire woman, Margaret Wombwell.
That same year he was appointed lieutenant-colonel of the 124th Regiment of Foot, but a year later the regiment disbanded, and St Leger took on the "Park Hill" estate in Firbeck, where he later bred and raced horses.
From 1768 to 1774, St Leger sat as MP for Grimsby.
Two years after leaving the Commons, and with the assistance of Charles Watson-Wentworth, 2nd Marquess of Rockingham, he established a two-mile race for three-year-old horses, on the Cantley Common in Doncaster.
This was to become the St. Leger Stakes.
In 1779, St Leger re-entered the army as colonel of the 86th Regiment of Foot.
He subsequently achieved the rank of brigadier general, before serving a period as the Governor of Saint Lucia.
His last posting was in Ireland, by which time he was a major general.
St Leger died on 19 April 1786.
He was buried in Saint Anne's Church, Dublin.
In addition to giving his name to the St Leger Stakes, the "St Leger Arms" public house in Laughton en le Morthen (two miles up the road from the Park Hill estate) is also named after Anthony St Leger.
