When first visited by the Spanish explorers in the early sixteenth century, northern Florida was inhabited by the Timucua family of Indians. Their territory was bounded approximately on the west by the Aucilla River, on the north by a line running just north of the present Georgia-Florida state line from the Aucilla River on the west to Cumberland Island on the east, and on the south by a line extending from Tampa Bay to Cape Canaveral.
