William Randolph II of Wilton (November 1681 – October 19, 1741), also known as William Randolph, Jr. or Councillor Randolph, was the Treasurer of Virginia and the oldest child of William Randolph and Mary Isham.
Randolph was born on the Turkey Island Plantation along the James River in Henrico County, Virginia in 1681 and resided there his entire life. He married Elizabeth Beverley (the daughter of Peter Beverley, a Speaker of the House of Burgesses and Treasurer of Virginia) around 1705 and the couple had five children that reached adulthood:
Randolph was a great-uncle of United States President Thomas Jefferson.
His brother, Richard Randolph married Major John Bolling's daughter, Jane Bolling, also a lineal descendant of Pocahontas. They had six children.
His brother, Sir John Randolph married Susanna Beverley (daughter of Peter Beverley, Speaker of the House of Burgesses and Treasurer of Virginia) on July 20, 1738.
The town of Westham, Virginia was established on land that had been owned by Randolph. When Randolph died, his son Beverley inherited Westham Plantation and planned to create the town of Westham on part of it to facilitate trade in the Piedmont region of Virginia. After Beverley's sudden death, Peter Randolph inherited his brother's land and completed work on the project – renaming the town "Beverley" in honor of his older brother – with help from William Cabell and Peter Jefferson. Jefferson was one of a number of important Virginians, including Carter Braxton, Joshua Fry, John Hunter, Robert Rose, and William Stith. who purchased lots in the new town. Peter Randolph eventually sold Westham Plantation to his younger brother, William, who in turn sold the property to William Byrd III.
