Brocke’s father was an alderman of Chester who married into a minor county family and was granted arms in 1580.
Brocke was returned for St. Ives at the general election of 1604 on the recommendation of the 4th marquess of Winchester. In the opening session he was appointed to the committee to recommend laws for continuance, repeal or revival (24 Mar. 1604), and chaired a bill committee to authorize justices of the peace to release debtors (31 Mar.), which he reported on 5 April.
In 1605 Brocke leased Longwood House from the bishop of Winchester, and in the following year he bought the nearby manor of Merdon.
During the third session Brocke’s main concern, as the scurrilous ‘Parliament Fart’ poem makes clear, was the Union.
Among various other business, Brocke chaired several private bill committees, including one to confirm the titles of those who had purchased the lands of Sir Jonathan Trelawny* (21 Feb.), which he reported four days later.
Having received a hogshead of claret from the Southampton corporation earlier in the year, Brocke proceeded to earn this consultancy fee by steering a bill through the House on behalf of Southampton’s merchants designed to confirm their exclusive trading rights against a challenge from London. He reported the bill on 5 June, and further contributed to heated debate on its third reading, after which it eventually passed.
In 1608 Brocke acted as counsel for Southampton against the royal butler Sir Thomas Waller* over the latter’s claim to prisage on imports of wine and, despite an adverse judgment, secured a satisfactory composition, for which he was appropriately rewarded with hogsheads of ‘very good’ sack and canary.
During the fourth session Brocke was named to 15 committees, around half of which were for private bills. He was among those appointed on 26 June 1610 to resolve the dispute over the discharge of old debts due to the Crown.
Brocke died on 16 Nov. 1611 of a ‘rupture’ brought on by his exertions at the Chancery bar.
