'Daniel O'Neill' (
c.1612,
Castlereagh–
24 October 1664,
Whitehall) was an
Irish army officer, politician and courtier.
Early life
O'Neill was the eldest son of Con MacNiall O'Neill, lord of
Clandeboye and his wife, Ellis (a paternal niece of
Hugh O'Neill, 2nd Earl of Tyrone). His father lost land after defeat at the
Siege of Kinsale, leaving O'Neill to inherit a small estate at a young age in 1619. He then became a
ward of Chancery and was raised in
England as a
Protestant. His estate was late given to
Hugh Montgomery, 1st Viscount Montgomery and O'Neill and his brother were granted an
annuity.
Army service
With little prospects in his native Ireland, O'Neill then served under
Lord Conway in the
Low Countries during the
1630s, gaining military experience and friends such as
Elizabeth of Bohemia and her husband,
Frederick V, Elector Palatine. Using these connections, he petitioned for his lands to be restored to him, but despite support by
William Laud,
Lord Arundel and
Charles I Louis, Elector Palatine, he was rebuffed by the
Lord Deputy of Ireland,
Sir Thomas Wentworth (later
Earl of Strafford). Waiting for his petitions to be accepted, O'Neill returned to the Low Countries in 1637 and saw action at the
Siege of Breda and later in the
Bishops' Wars, where he was captured at the
Battle of Newburn and imprisoned at
Newcastle upon Tyne.
Plotting and imprisonment
After O'Neill's release, he conspired to overthrow Wentworth but the discovery of the subsequent plots he became involved in, forced him to flee to
the continent in mid-June of 1641. Hoping for
immunity, he returned to England a few months later and surrendered to
John Pym, but was sent to
Gatehouse Prison to await his trial. His health began to suffer and in 1642, he was petitioned for better treatment and was transferred to the
Tower of London where he escaped by tying
bedsheets and a
tablecloth together and dressing as a woman.
Royalist cause
Fleeing to
Brussels, O'Neill gathered troops and arms for the royalist campaigns in the
English Civil War, served under
Prince Rupert of the Rhine and fought at
Edghill,
Chalgrove Field and the
First Battle of Newbury.
After failing to secure negotiations in the
Irish Confederate Wars, O'Neill went on to serve as a
spy to the ''
de jure''
Charles II at
The Hague.
The Restoration
Following
The Restoration in 1660, O'Neill was rewarded and appointed to money-making positions by Charles II, including: as a
Groom of the Bedchamber,
Captain in the
Horse Guards,
Member of Parliament for
St Ives, admittance to
Gray's Inn,
mining rights, monopoly of the manufacture of
gunpowder to
The Crown, warden of
St James's Palace,
Postmaster General and accountant for the regulation of
ale houses. He subsequently became one of the richest men in the kingdom. In 1662, he married his old friend, the
Countess of Chesterfield and built
Belsize Park for her. On his death in 1664, he left everything to his wife and was buried in the church of
St Nicholas at
Boughton Malherbe, his wife's estate.
