The illegitimate son of a senior member of the Cheshire gentry, Aston appears to have been raised entirely in Scotland. By 1580 he was master huntsman to James VI, and in 1587 was appointed to the king’s chamber. He enjoyed a familiar relationship with James, who tried to persuade him to take up smoking and to ‘put him out of his new custom, which is to drink nothing but ale after supper’.
Aston remained one of the king’s closest confidants and regular hunting companions after James ascended the English throne. Like many Scottish courtiers, he benefited greatly from James’s generosity, being appointed a gentleman of the bedchamber and receiving numerous offices and grants of lands, including the keeperships of various parks and houses.
Although Aston no longer lived in Cheshire the county returned him to Parliament in 1604. Cheshire had a tradition of electing one Member connected to the Court, and it helped that Aston was drawn from one of its senior gentry families. Aston may have sought election at the king’s suggestion, as James needed someone close to him to inform him of activities in the Commons. Throughout the Parliament, certainly, Aston was often employed as a messenger between James and the Lower House. On 11 Apr. 1604 he conveyed the Commons’ gratitude after James allowed Members to decide for themselves the outcome of the Buckinghamshire election. He also informed the Commons that the king would meet them the following day, and was among the delegation sent to James on 12 April.
Aston was named to 21 bill committees in 1604. Most concerned matters that must have particularly interested James, such as the naturalization of the Scottish courtiers Sir George Home (18 May) and John, earl of Mar (11 June), the confirmation of letters patent granted to Home (18 May), the renewal of Berwick-upon-Tweed’s charter (16 May) and the jointure of Anne of Denmark (24 May).
In 1605-6 Aston continued to serve as both the king’s eyes and ears in the Commons and as a messenger. As a reporter he proved so assiduous that Salisbury was once rebuked by James because Aston’s report of a conference on ecclesiastical causes was more detailed than his. Aston’s dispatch was ostensibly directed to Thomas Erskine, Lord Dirletoun, and from it James learned of a new bill of purveyors in May 1606.
In 1606 Aston was appointed to naturalization bills concerning the Scottish courtiers Sir David Foulis (18 Apr.) and Sir David Murray (14 May), and was named to consider the measure confirming a land sale for his fellow courtier Sir Thomas Lake I* (25 January).
At the opening of the third session (1606-7), the king’s reply to the grievances’ petition was read. Aston was obliged to surrender his patent for the greenwax, but an amended grant was then issued which barely affected his income from this source.
It has been claimed that in the fourth session (1610) Aston was ‘particularly active’ in persuading the king to accept the Great Contract, but the evidence does not sustain this assertion.
Aston fell terminally ill in May 1612 and was visited while on his sickbed by James.
