Smith must be distinguished from Sir William Smith† of Theydon Mount, Essex (d.1626) who, like him, was a Londoner by birth. The latter spent much of his early life involved in ventures to plant and subdue Ireland and in 1605 accompanied the embassy of the 1st earl of Nottingham (Charles Howard†) to Spain.
In the first session Smith was appointed to two private bill committees, for the jointure of the wife of Martin Calthorpe (27 Apr. 1604), and the naturalization of the chancellor of the Exchequer, Sir George Home (18 May).
In the third session Smith promoted a second private bill, brought down from the Lords on 30 Mar. 1607, to confirm his ownership of the Leicestershire manor of Whadborough and various ex-monastic properties in the same county, which he had purchased from All Souls’ College, Oxford. At its third reading on 8 May the latter measure was queried by Sir John Townshend and Sir William Strode, and accordingly the bill was recommitted. It passed the House three days later, after it was agreed that it should include a proviso offered by Smith himself.
In 1612 Smith joined a syndicate of contractors for the sale of rectories, parsonages and other Crown property that included among others Sir Walter Cope*, Sir Baptist Hicks*, Arthur Ingram*, Sir Thomas Lake I*, Sir Thomas Myddelton*, William Pitt* and Thomas Watson*. By this time Smith seems to have been fairly prosperous, as he donated the generous sum of £20 towards the Benevolence in 1614,
Smith had sold off his Leicestershire property by 1615, when he bought the manors of Cumberloe Green and Rushden in Hertfordshire.
In July 1620, two months after undergoing surgery to remove a large bladder stone, Smith died suddenly despite, as Carleton learned from his friend John Chamberlain, having at first ‘seemed to be well healed and held out so long’.
