John Minor was a planter in Louisiana when it was under Spanish rule.
Stephen (Estevan) Minor (1760-1815), John's brother, was a Spanish government official on the Spanish-American frontier in the Lower Mississippi Valley, a planter, and organizer of the Bank of Mississippi at Natchez. He accompanied two expeditions along the Natchez Trace to Choctaw Indian villages, which led to the signing of the Natchez Treaty of 1792; and as boundary commissioner (1797-1798) he acted in concert with Andrew Ellicott in drawing the thirty-first parallel as the boundary across Florida. In 1797, Spanish governor Manuel Gayoso de Lemos appointed him last Spanish governor (ad interim) of the Natchez District (1797-1798).
