Henry Portman

Henry William Portman (1738 - 11 January 1796) was an 18th-century housing developer, the ancestor of the Viscounts Portman.

Biography
He was the son and heir of Henry William Berkeley Portman MP (d.1761), by his wife Anne Fitch. His grandfather was William Berkeley (d.1737) of Pylle, Somerset, who had changed his surname, by private Act of Parliament (9 Geo. 2. c. 22), to Portman on becoming heir to his distant cousin Sir William Portman, 6th Baronet (d.1690) of Orchard Portman, Somerset —as well as quartering the Portman arms with his own. He succeeded his father in the estates of Bryanston and Orchard Portman in 1761, and to the Berkeley estates at Pylle on the death of his aunt Lady Burland. He developed 200 acre of meadow in London (between Oxford Street and the present site of Regent's Canal) he had inherited from his Tudor ancestor Sir William Portman, turning it into the Portman Estate. He began issuing its first building leases in 1755, and building began in 1764 with Portman Square, which was to owe its popularity to buildings by Robert Adam and James ‘Athenian’ Stuart.

Marriage and Issue
On 20 January 1766, he married Anne Wyndham, daughter of Sir William Wyndham, of Dinton House, Wiltshire, by whom he had two sons and three daughters.

Three weeks after the wedding his father signed a new will, in which Henry was disinherited and the Portman properties left to his younger son (possibly because Lord Dormer was a Roman Catholic). Henry was elected M.P. for Wells in 1790, but withdrew from parliament after the disagreement with his father. He and Lucy had one daughter, Charlotte Fanny (1797-27 March 1877), who was born at Barrells Hall, in Warwickshire, the home of Robert Knight (who was married to Lucy's sister). Still resident at Barrells Hall, on 28 August 1820, Charlotte Portman married John Poulett, 5th Earl Poulett & had issue.
