Green Clay, an American soldier, born in Powhatan co., Virginia, Aug. 14, 1757, died Oct. 31, 1826. Prompted by the example of Boone's adventurous career in Kentucky, he migrated to that district before he was 20 years of age, and entered the office of a surveyor, whose deputy he soon became; afterward he engaged in the surveying business on his own account, and by locating lands laid the foundation of a fortune. He was a representative of the Kentucky district in the Virginia legislature; was a member of the Virginia convention which ratified the federal constitution of 1789, in favor of which he spoke and voted; and was a leading member of the convention which formed the Kentucky constitution in 1799. He served for a long time in both branches of the state legislature, and was speaker of the senate. In 1813 he led 3,000 Kentucky volunteers to the relief of Gen. Harrison, then besieged in Fort Meigs by the British. He cut his way through the hostile lines, and this accession of strength to the fort forced the enemy to withdraw.

Gen. Harrison left him in command of Fort Meigs, which was soon after unsuccessfully attacked by a large force of British and Indians under Gen. Proctor and the famous chief Tecumseh. For his skilful conduct of this defence, Gen. Clay received the special thanks of Gen. Harrison. At the close of the war he retired to his estate in Kentucky, and devoted the remainder of his life to agricultural pursuits.
