Nothing has been ascertained of Watson’s parentage and early life. He should be distinguished from the Elizabethan poet of the same name, and he was probably not the Thomas Watson of Worcestershire who was educated at Oxford and the Middle Temple during the early 1580s, as it seems to have been this man who subsequently became an alderman of Evesham.
On the restoration of peace in Ireland, Cecil procured for him a reversion of one of the four tellerships in the Exchequer at Westminster.
In March 1614 Watson was elected to Parliament for the borough of Rye. He probably owed his return to Sir Thomas Lake I whom he later termed ‘honest Sir Thomas Lake’.
In September 1614 Watson personally notified the Privy Council that he and his colleagues on the Kent bench had arrested the itinerant minister Josias Nicholls, who had incited non-payment of the Benevolence demanded by the Crown following the dissolution of Parliament.
Watson drew up his will on 1 July 1621 and died on 30 Oct. following, owing the king over £14,900 and his daughter more than half her marriage portion of £5,000. He blamed the size of his debts on the fact that, along with Thomas Warre* and Sir Robert Heath*, he stood engaged in several ‘great and grievous bonds’. He bequeathed a Surrey rectory to John Murray, to whom he declared himself ‘very much beholden for his abundant favours and kindnesses’. It may have been through this connection that his widow married William Murray, a Cambridge don who became a bishop in Ireland and Wales. Each of his overseers, (Sir) George Marshall*, his brother-in-law John Worsopp of Windsor, and his clerk George Smith of Mitcham, was to receive a horse from his stables.
