When William Lacon first appears in the records he was a younger son. In Michaelmas term 1439, as ‘of Willey, gentleman’, he was sued for trespass by William, Lord Lovell. More significantly, on 14 Apr. 1445, with his father and brothers, he was implicated in the murder of a yeoman at Stockton-on-the-Forest near York, and he was appealed by the yeoman’s widow in the following February. Here the Lacons appear to have been acting as servants of the Talbots – there is no other ready explanation for their appearance in a county so distant from their native Shropshire – and it was this service that was to transform William’s prospects. According to the Berkeleys’ historian John Smyth, working from now lost documents, ‘one Lacon’ was killed by his own servant while acting for Margaret, wife of John Talbot, earl of Shrewsbury, in the Talbots’ famous dispute with the Berkeleys; and there is every reason to suppose that the victim was William’s elder brother, Richard.
Lacon’s term as sheriff came at a difficult time. In February 1452 Richard, duke of York, rose against the government, drawing significant support from Shropshire, and in the following August royal justices of oyer and terminer came to the county to take indictments of those involved. It fell to our MP as sheriff to facilitate the justices’ inquiry by the requisite juries and executing process against the indicted. Such tasks often led sheriffs into difficulties, but Lacon seems to have managed adroitly. He satisfied the Crown by arresting two of the more prominent men indicted as supporters of York, Fulk Eyton and Roger Eyton*, but avoided local unpopularity by returning ‘not found’ to the many other writs of capias.
A term as sheriff early in a career generally marked a man out for a prominent path in local administration, and Lacon, had he lived, would have been no exception. On 1 Mar. 1453 he was elected to represent the county in Parliament in company with (Sir) John Burgh III*, who returned himself; and, on the following 16 July, shortly after the end of the second session of the Parliament, he was named to the county bench.
At least two matters troubled Lacon during his brief period as head of his family. On 29 June 1456 he was outlawed in the city of Coventry for a debt of £40 claimed against him by the city’s recorder, Henry Boteler II*, an humiliation for a man of his standing.
