Thomas Herbert, 8th Earl of Pembroke

Herbert was the third son of Philip Herbert, 5th Earl of Pembroke and his wife Catharine Villiers, daughter of Sir William Villiers, 1st Baronet who was the half-brother of the 1st Duke of Buckingham, George Villiers. Through his grandmother, Susan de Vere, he was a great-grandson of Edward de Vere, 17th Earl of Oxford, the Oxfordians' William Shakespeare. He was educated at Tonbridge School, Kent. Both of his brothers (the 6th Earl and the 7th Earl) having died without a male heir, he succeeded to the earldoms in 1683. Through them, he would inherit the family seat of the Earls of Pembroke, Wilton House in Wiltshire.
