Arthur Hill, 2nd Marquess of Downshire

Arthur Hill, 2nd Marquess of Downshire PC, FRS (3 March 1753 – 7 September 1801), styled Viscount Fairford until 1789 and Earl of Hillsborough from 1789 to 1793, was a British peer and MP.

[3] Hill enjoyed a number of civil and military appointments in both England and Ireland during this period.

Hillsborough, as he then was, was chosen a Fellow of the Royal Society on 22 January 1790 and a deputy lieutenant of Berkshire on 12 May 1792.

[5] On 29 June 1786, he married Mary Sandys, by whom he had seven children: His last son, Lord George Hill, was born posthumously, as Downshire died by suicide on 7 September 1801.

His widow, Mary, felt his early death was in part due to his humiliation by the Government, and thereafter was a bitter enemy to Robert Stewart, Viscount Castlereagh.
