Mr. Grey was born March 13, 1764, and educated at Eton, in the same class with the late Mr. Lambton, (father of the present Lord Durham,) Mr. Whitbread, and others, with whom he afterwards acted in political life. He was then sent to King's College, Cambridge, where he displayed first-rate abilities. On his leaving the University, he set out on the tour of Europe, though only eighteen years of age. In Italy, he was introduced to the late Duke of Cumberland, in whose household he obtained an appointment. He returned to England in 1786, and soon after his arrival, was, by the interest of his family, returned to parliament for the county of Northumberland, when he joined the Whigs, it has been stated, to the surprise of his family, whose principles were those of Toryism. At a subsequent general election, as an expensive contest was expected for Northumberland, Mr. Grey declined nomination, and was returned to parliament for Appleby, which borough he represented till his succession to the peerage. In the House of Commons his great talents soon shone forth; and, in conjunction with Fox, Sheridan, Lambton, Ponsonby, and others, he maintained an intrepid opposition to the doctrines of that darling of fame, Mr. Pitt. Immediately after his entrance into Parliament, his discussion of the minister's important treaty of commerce, may be said to have established his reputation, by the force of his eloquence, as well as by the enlarged views which he seemed to have acquired of commercial relations; which knowledge is more frequently the result of gradual experience than of early attainment. In these stormy times Mr. Grey ranked among the head and front of contending politics. He was appointed one of the managers of that magnificent political drama--the impeachment of Warren Hastings, when he displayed great acumen in that part of the accusation termed the Benares Charge.
