Gamull received none of the benefits of the gentleman’s education bestowed on his elder brother, Thomas, but instead followed his father into commerce. He appears to have mainly traded in French wines, importing at least 44 tuns from Gascony in 1601.
A prominent figure in Chester’s municipal affairs, Gamull undertook the onerous position of sheriff in 1602-3 which entailed thrice weekly sittings of the Sheriffs’ Court as well as presiding over the Passage Court every five weeks.
Like many corporation officials, Gamull benefited from his civic status, leasing the fee farm of Newgate and the ‘old tower’ adjoining it for 33s. 4d. p.a. in 1618.
On the outbreak of Civil War Gamull evidently supported the king. In September 1642 he was appointed to search the houses of three suspected parliamentarian sympathizers, one of whom was Sir William Brereton, 1st Bt.*, for arms.
