William Smith (1721–1803) was an English civil servant who held the post of Treasurer of the Ordnance throughout the French Revolutionary Wars.
In the 1784 general election, the Duke persuaded him, against the advice of family and friends, to stand for the seat of Chichester which returned two MPs.
The contest became heated, with Smith coming under personal attack over his public and his private life, and on polling day of 1 April 1784 he came last with only 23% of the vote.
Six months and a day after the Admiral's death, at the church of St Marylebone on 24 November 1783, he married Anne and became stepfather to her children.
Her younger sister Louisa Mary Smith (1789–1850) in 1810 married John Edward Jones (1786–1854), a Royal Artillery officer who became a Major-General,[12] and had eight children.
