History of Harris County
Human remains date habitation to about 4000 BC. Other evidence of humans in the area dates from about 1400 BC, 1 AD, and later in the first millennium. The region became uninhabited from 1 AD to European contact. Little European activity predates 1821. Álvar Núñez Cabeza de Vaca may have visited the area in 1529. French traders recorded passing through in the 18th century. Spaniards attempted to establish a fort in the area around the same time, but did not persist for long. The first recorded European settlers in Harris County arrived in 1822. Their schooner sailed into Galveston Bay and ran aground on the Red Fish Bar. Some of those passengers traveled further up the bay system, but it is not known whether they settled up Buffalo Bayou or the San Jacinto River. One of these passengers, a Mr. Ryder, settled at what is now known as Morgan's Point, Texas.
