Alexander Mcgillivray, a chieftain of the Creek or Muscogee Indians, born on the Coosa river near the present site of Wetumpka, Ala., about 1740, died in Pensacola, Feb. 17, 1793. He was the son of Lachlan McGillivray, a Scotch Indian trader, and the half-breed daughter of a French officer. He was educated in Charleston, and at one time was placed in a counting house in Savannah, but returned on arriving at manhood to his Muscogee relatives. He rose to a high position among the united tribes of Creeks and Seminoles, and at the breaking out of the American revolution was their recognized head. During the war the McGillivrays, father and son, were zealous adherents of the royal cause. After its close Alexander McGillivray, in behalf of the Muscogee confederacy, entered into an alliance with Spain, of which government he was made a commissary. He diverted the trade of the Creeks to Pensacola, and for several years baffled the efforts of the United States government to recover it. At length, in 1790, he visited New York, and signed a treaty ceding certain disputed lands on the Oconee, and by a secret article was appointed agent for the United States and brigadier general in the army.

This treaty diminished his influence with the Creeks, but he succeeded in obtaining an increase of salary and of authority from the Spanish government. His hospitality and generosity were almost princely. His deportment was that of a polished gentleman; and his published correspondence affords evidence of his intelligence and skill as a politician. He was a brother-in-law of Le Clerc Milfort, and an uncle of William Weatherford.
