Henry Portman, 2nd Viscount Portman

Portman was elected to Parliament for Shaftesbury in 1852, a seat he held until 1857,[2] and then represented Dorset from 1857 to 1885.

At the end of the nineteenth century the 99-year leases on the family properties in London came up for renewal, generating a colossal income for Lord Portman of some £100,000 a year.

With this fortune he commissioned Norman Shaw to build a new mansion for him at the family seat in Bryanston, Dorset.

Son of Edward Portman, 1st Viscount Portman (9 July 1799 – 19 November 1888) and Lady Emma Lascelles (16 March 1809 – 8 February 1865) William Henry Berkeley Portman married Mary Selina Charlotte FitzWilliam (9 Jan 1836 – 3 January 1899), daughter of William Charles FitzWilliam (18 Jan 1812 – 8 November 1835), son of the 5th Earl Fitzwilliam,(1786–1857) and Lady Selina Charlotte Jenkinson, daughter of the 3rd Earl of Liverpool, on 21 June 1855.

In 1908 he married, secondly, shortly before his 79th birthday, Frances Maxwell Buchanan Cuninghame, by whom there were no further children.
