20 The Randolph family in Virginia is commonly traced to William Randolph of Turkey Island, the younger son of Sir Richard Randolph of Morton Hall, Warwickshire, who came to Virginia in 1673. But the true beginning of the family in Virginia was Henry Randolph, the third son of William Randolph of Northamptonshire who emigrated ca. 1650. William Randolph of Turkey Island married Mary Isham, grandaughter of Sir Henry Isham of Braunston, Northamptonshire. Her sister Anne Isham married Francis Eppes in Virginia. The Ishams and Randolphs intermarried in both England and Virginia. See VCH Northamptonshire Genealogies, plus ms. genealogies in NHANTRO.
