Berkeley Hundred in the Virginia Colony comprised about eight thousand acres (32 km²) on the north bank of the James River near Herring Creek in an area then known as Charles Cittie (sic). It later became known as Berkeley Plantation, and was long the traditional home of the Harrison family, one of the First Families of Virginia.
Berkeley Hundred was a land grant in 1618 of the Virginia Company of London to Sir William Throckmorton, Sir George Yeardley, George Thorpe, Richard Berkeley, and John Smyth (1567–1641) of Nibley. Smyth was also the historian of the Berkeley group, collecting over 60 documents relating to the settlement of Virginia between 1613 and 1634 which have survived to modern times.
In 1619, the ship Margaret of Bristol, England sailed for Virginia under Captain John Woodliffe and brought thirty-eight settlers to the new Town and Hundred of Berkeley. The London Company proprietors instructed the settlers that "the day of our ships arrival . . . shall be yearly and perpetually kept as a day of Thanksgiving." The Margaret landed her passengers at Berkeley Hundred on December 4, 1619. The settlers did indeed celebrate a day of "Thanksgiving", establishing the tradition two years and 17 days before the Pilgrims arrived aboard the Mayflower at Plymouth, Massachusetts to establish their Thanksgiving Day in 1621.
On March 22, 1622, Opchanacanough, head of the Powhatan Confederacy, began the Second Anglo-Powhatan War with a coordinated series of attacks against English settlements along the James River, known in English histories as the Indian massacre of 1622. Nine colonists were killed at Berkeley. The assault took a heavier toll elsewhere, killing about a third of all the colonists, and virtually wiping out Wolstenholme Towne on Martin's Hundred and Sir Thomas Dale's progressive development and new college at Henricus. Jamestown was spared through a timely warning and became the refuge for many survivors who abandoned outlying settlements. A myth about the March 22 date was that it occurred on Good Friday. This is incorrect.
