The Old Three Hundred were the 297 grantees, made up of families and some partnerships of unmarried men, who purchased 307 parcels of land from Stephen Fuller Austin and established a colony that encompassed an area that ran from the Gulf of Mexico on the south, to near present-day Brenham in Washington County, Texas, Navasota in Grimes County, and La Grange in Fayette County. Moses Austin was the original empresario of the Old Three Hundred and was succeeded by his son, Stephen F. Austin, after his untimely death.
