Hervey was the last of a younger branch of the Ickworth family founded by his grandfather.
Early in James’s reign Hervey was granted the office of remembrancer of ecclesiastical first fruits and tenths in the Exchequer in reversion to Sir Edward Stafford*. He held St. Andrew’s Castle on the Hampshire coast on a grant dated 12 Aug. 1578, and probably resided at Soberton, ten miles from Petersfield, during his first marriage.
Hervey’s first wife died in 1607, leaving him much of the spoils of her late second husband’s adventuring.
Hervey was appointed to help investigate the Navy following the failure of Lord Willoughby’s expedition in 1626. An active member of the commission, he submitted a proposal for the defence of the coasts and Channel in February 1627.
