The farm and manor house of Greenland are the property of Thomas Darby Coventry, Esq.
In May, 1644, Sir John Doyley garrisoned and fortified it for the King, with a view of commanding the passage of the Thames from Henley and Reading to the Metropolis. After sustaining a long and severe siege from the parliamentary forces, under Major General Brown, the house being nearly reduced to ruins by the batteries on the opposite side of the river, it was surrendered on honourable terms in July, by its governor, Colonel Hawkins. The farm exhibits very considerable traces of the buildings and fortifications.

1853: Greenlands extended for Edward Marjoribanks
1871: Greenlands extended for W. H. Smith.
1881: George Leslie, "Our River"

[Greenlands] is the well-known residence of the Rt. Hon. W. H. Smith, and has been by him considerably enlarged;  it is I believe, a comfortable house, but the contrast of the dark cedar trees around gives it rather a sombre effect.  There are some fine inland ponds near, where skating in the winter is very good;  these ponds and the ditches and flat meadows about are favourite haunts of heron and lapwing.

1881: The Census records show W H Smith at home with his wife, 3 daughters, and 16 servants.

1889: Jerome K Jerome -

... Greenlands, the rather uninteresting looking river residence of my newsagent - a quiet unassuming old gentleman, who may often be met with about these regions, during the summer months, sculling himself along in easy vigorous style, or chatting genially to some old lock-keeper, as he passes through

Neither George Leslie nor Jerome K Jerome quite does justice to William Henry Smith, founder of Smith's book and stationery chain.
In 1846 his father W H Smith Senior had made him a partner in the family news agency in London's Strand.  By then the railways were beginning to change the face of Britain and the younger Smith had negotiated with the major rail companies for permission to erect bookstalls at stations. He got rid of the cheap, salacious material for which railways had become infamous, causing Punch to give him the nickname 'Old Morality.' This enhanced his reputation and very soon he had exclusive rights on all major stations to sell the magazines and journals that now proliferated with the repeal of Stamp Duty.
In 1868 he was eventually elected to Parliament as Member for Westminster and became a loyal Tory backbencher and minister. In 1877 he joined the Cabinet as First Lord of the Admiralty.
He was immortalised by Gilbert and Sullivan in HMS Pinafore as Sir Joseph Porter, the admiral who had never been to sea -

'A junior partnership was the only ship I had ever seen'.
I always voted at my party's call
And never thought of myself at all
Thought so little, they rewarded me
So now I am the ruler of the Queen's navy.

W H Smith became known as 'Pinafore Smith'.  He died in 1891 at Walmer castle, his official residence as warden of the Cinque Ports.

1936-8: Further alterations were made to the west front by P. Geddes Hyslop.
