Croke had no property of his own, and depended entirely on the profits of office and the estates he enjoyed in the right of his two wives, the first an heiress, the second an exceptionally well-dowered widow.
The appearance of the Croke brothers in the Commons in 1628 for the first time since 1614, together with Rous, who had never sat before, suggests that a counter-attack on the efficient Sawyer was planned before Parliament met. Croke’s brother was returned for Shaftesbury, while he himself stood unsuccessfully for Oxford on the Knollys interest, but was elected for Christchurch on the nomination of Lord Arundell.
Croke failed to stifle criticism of the Pipe office, for which he assumed sole responsibility on Rous’s death in 1632. In 1635 his own deputy, Christopher Vernon, attacked his record on two fronts, accusing him of extortion to the tune of £10,000, and of laxity in recovering debts collected by the sheriffs.
