A Cheshireman who settled in London, by 1590 Moulson was involved in the cloth trade at Stade, perhaps as an associate of Lionel Cranfield*, sending kerseys to Nuremberg. He remained in northern Germany until at least 1600. On his return he married the daughter of a wealthy Merchant Taylor, settling in the London parish of St. Christopher-le-Stocks and continuing his overseas business through factors.
On his return from Germany Moulson assumed a prominent position in his parish, joining the vestry and, until 1623, helping to audit the churchwarden’s accounts.
In April 1624 Moulson, as governor of the Merchant Adventurers, testified before the Commons’ committee for trade that, following the disastrous Cockayne Project, the Company had been compelled to pay the king £50,000 to have its charter restored.
During the 1628/9 sessions Moulson was named to one joint conference with the Lords and 18 committees, of which ten were concerned with trade. One of these was concerned with drafting a calendar of all the shipping lost since the outbreak of the war with Spain, to which he was appointed on 14 June, five days after speaking on the capture by the Dunkirkers of nine ships laden with masts.
One of the committees to which Moulson was named concerned a bill for suppressing unlicensed alehousekeepers (17 April). This appointment was typical of his concern to reform the morals of the lower orders, for during the 1630s he presented numerous cases of prostitution, bastardy and petty crime to Bridewell Hospital.
When Moulson drew up his will he claimed to be in good health, but seven months later he reportedly declined the presidency of Christ’s hospital ‘in respect of his great weakness and infirmities of body’.
