Lord Henry Seymour (politician)
Lord Henry Seymour( 15 December 1746 – 5 February 1830) was a British politician, the second son of Francis Seymour- Conway, 1st Marquess of Hertford.
He was known as Hon. Henry Seymour- Conway until 1793, when his father was created a marquess; he then became Lord Henry Seymour- Conway, but dropped the surname of Conway after his father's death in 1794.
Seymour- Conway was educated at Eton and Hertford College, Oxford, and took his MA from Merton College in 1767.
He was first elected to the House of Commons in 1766 as Member for Coventry.
He generally, though not always, voted with his uncle and namesake Henry Seymour Conway.
After the 1768 election, when he and Andrew Archer defeated a challenge by Walter Waring, he was a consistent supporter of the Grafton and then the North governments.
Due to a falling- out between his father, the Earl of Hertford, and the Corporation of Coventry, Seymour- Conway did not stand as a candidate there at the 1774 election.
He was instead returned by the North administration at Midhurst, which was a Treasury borough that year.
In 1776, he was also returned to the Parliament of Ireland for Antrim County, which he represented until 1783.
As his re-election in Midhurst did not appear to be sustainable in the 1780 election, he stood successfully at Downton.
In the 1784 election, Seymour- Conway and Robert Shafto faced off against Hon. Edward Bouverie and William Scott, and, a double return being made, the case came before the House of Commons.
Seymour- Conway chose not to stand in the ensuing by-election; his brother William took his place and won the by-election.
During this period, he was for some time a captain in the Warwickshire Militia, and befriended the poet George Crabbe while quartered at Aldeburgh.
On 11 February 1793, he was promoted major.
The election of 1784 marked Henry's retirement from politics.
In 1790, he and his brother Robert were jointly granted, for life, the sinecures of joint prothonotary, clerk of the crown, filazer, and keeper of the declarations of the King's Bench in Ireland.
By 1816, these offices brought an income of more than £ 10,000 a year( equivalent to £ as of).
He was also craner and wharfinger of the Port of Dublin, a sinecure abolished in 1830.
He spent the rest of his life in the improvement of his estate at Norris Castle, in the Isle of Wight, where he experimented with the use of seaweed as a fertiliser.
He had a reputation for both eccentricity and benevolence when he died, unmarried, in 1830.
There is a memorial to him in St. Mildred's Church, Whippingham.
He left Norris Castle to his youngest brother Lord George Seymour, who sold it to newspaperman Robert Bell in 1839.

By 1816, these offices brought an income of more than £ 10,000 a year.
He returned to Parliament for Orford in 1794, and continued to hold the seat until 1807.
He took some interest in agriculture, as in 1796, he invented a new one- horse cart.
On 2 December 1803, he was appointed Lieutenant- Colonel Commandant of the 2nd Battalion, Carmarthenshire Volunteers.
He resigned that command on 6 January 1808.

During the 1807 election, Seymour was returned both for Orford and Carmarthenshire, choosing to sit for the latter, which he represented until 1820.
On 1 July 1807, Seymour, who owned a house in Portland Place, was sworn a Justice of the Peace for Middlesex.
He took an active role in civic affairs in London, and was for some time Director of the Poor for his parish of St Marylebone.
This included a particular interest in the care and treatment of the insane, culminating in his appointment in 1827 to the commission superintending the building of Hanwell Asylum and as a Metropolitan Commissioner in Lunacy in 1828.
However, he was now approaching the end of his life and played little active role as a Lunatic Commissioner.
In 1829, Seymour funded the building of the north transept and a vicarage for Taliaris Chapel.
