Herbert was a younger brother of Edward Herbert, Baron Herbert of Cherbury. His role as Master of the Revels involved reading and licensing plays and supervising all kinds of public entertainment. Herbert was succeeded by his son Henry, for whom the barony of Cherbury was revived.
Henry junior died in January 1709, and his son, another Henry, became 2nd Lord Herbert of Cherbury of the second creation. He died without issue in April 1738, and again the barony became extinct. In 1743 it was revived for Henry Arthur Herbert (c. 1703-1772), who five years later was created Earl of Powis. This nobleman was a great-grandson of the 2nd Lord Herbert of Cherbury of the first creation, and since his time the barony has been held by the Earls of Powis.
