Edward Villiers (1656-1711) was raised to the peerage as Viscount Villiers of Dartford and Baron Villiers of Hoo.
The line is:
First Earl: Edward Villiers 1656-1711 Second Earl: William Villiers (son) 1682?- 1721 Third Earl: William Villiers (son) d.1769 Fourth Earl: George Bussey Villiers (son) 1735-1805 Fifth Earl: George Child Villiers (son) 1783-1859.
It would appear that your document refers to the second or third earls (about 1711 or 1721).
Would need more information to decide which. Is a monarch and/or a regnal year mentioned?
