Educated in France,[1] Waldegrave inherited his father's title in 1690, and, on 20 May 1714, he married Mary Webb (who died in childbirth in 1719), a daughter of Sir John Webb, 3rd Baronet and they had three surviving children: After the death of his wife, he returned to England from the Jacobite court in exile and converted from Roman Catholicism (the religion he was brought up in) to Anglicanism in order to take his seat in the House of Lords.

[1] During his ambassadorship to France, he still spent enough time in London to be one of the founding Governors of the new charity there, known as the Foundling Hospital (created in 1739).

In 1729, he had been created Earl Waldegrave and on his death in 1741, was succeeded by his eldest son, James.

Sir James inherited Hever Castle in Kent which had remained in the Waldegrave family for 160 years.
