Gerard succeeded to the family estates and title as a child of five. He remained in the care of his mother and her second husband, Sir Edward Hungerford‡, until his marriage in 1678 to a distant cousin. Gerard then joined his wife to live in the household of his father-in-law, though this appears to have been a short-lived arrangement and he soon returned to live with his mother and stepfather.
Coming of age after the dissolution of the Oxford Parliament and dying before the calling of James II’s Parliament, Gerard never took his place in the House of Lords. He was nevertheless included upon two parliamentary lists compiled in the late 1670s. In 1677-8 Anthony Ashley Cooper, earl of Shaftesbury, included Gerard upon his assessment of lay peers, noting only that Gerard was then underage. In 1679 Gerard was listed by Thomas Osborne, earl of Danby, (later duke of Leeds) among those peers absent from the Lords and who were not Catholic. Danby classed Gerard as a probable court supporter, a judgment that might have been grounded in the perceived influence of Gerard’s father-in-law, who at this stage was also regarded as loyal to the court, and/or as a result of the abortive negotiations the previous year for the marriage of Gerard to one of Danby’s daughters.
Gerard appears to have been an impetuous and short-tempered youth. When he was only 14 he drew his sword during a scuffle with a social inferior and ran his opponent through the groin.
