His eldest surviving brother John Robinson became Bishop of London and his sister Clara married Sir Edward Wood, Gentleman Usher to Queen Catherine.
[3] In 1672, Britain chartered the Royal African Company, and Robinson, his Middlesex neighbor William Churchill and Dudley Digges of Gloucester County were their local agents by 1685.
[6] Thus, he held office during Bacon's Rebellion, in which he supported Governor Berkeley, who was removed by the Board of Trade shortly afterward.
Middlesex County voters first elected Robinson as one of their representatives to the House of Burgesses in 1685 (when Robert Beverley was prevented from taking the other seat, having become clerk of that body), and re-elected him until his elevation to the Virginia Governor's Council.
His area of influence grew in 1787 because of the death of Robert Beverley, who had helped suppress Bacon's Rebellion, in part because Robinson married the widow.
Agatha died January 25, 1686 (by today's calendar), and her passing was recorded in the Register of Christ Church Parish in Middlesex County.
Robinson remarried, to Katherine Hone, the widow of fellow burgess Major Robert Beverley, on September 17, 1687, in Middlesex County.
