Guildford Onslow

Guildford James Hillier Mainwaring-Ellerker-Onslow (29 March 1814 – 20 August 1882[1]) was an English Liberal Party politician who sat in the House of Commons from 1858 to 1874.

[2] His father started a relatively briefly second-ranking branch of the Earl of Onslow's family, the land owning and land-developing heirs of much of the land of the Earls of Surrey which in 1870 became the senior branch of the family on the accession to the earldom of Guildford Onslow's nephew.

He was educated at Eton College and joined his father's regiment, the Scots Fusilier Guards.

[2] In October 1858, Onslow was elected at a by-election as one of the two Members of Parliament (MP) for Guildford in Surrey.

[3] In 1861 he assumed by Royal Licence the additional surnames of Mainwaring and Ellerker.
