William McGillivray (native name Coahoma) was a leader of the Chickasaw people of North America in the 18th and 19th centuries.
Along with James Brown and William Colbert, he was one member of a Chickasaw delegation that met with George Washington in 1795.
[1] The delegation was accompanied by interpreter Malcolm McGee and Robert Hays, a brother-in-law of Andrew Jackson.
An inhabitant of Holly Springs in years gone by says of him: 'McGillivray was a very old man, had served under Washington, and was commissioned by him as captain of the United States army, and stationed at Fort Pitt, now Pittsburgh, Pa., in the old war.
"[4] In 1805, McGillivray was a signatory to the Treaty of the Chickasaw Nation signed at or near the home of Wolf's Friend on July 23.
