Henry Howard, 5th Earl of Suffolk (18 July 1627 – 10 December 1709) was the youngest son of Theophilus Howard, 2nd Earl of Suffolk, but inherited the title, because none of his brothers left surviving sons.
He married three times:
Mary Ronkswood advanced £500 (shortly before her marriage) towards the capital of the lead smelting enterprise of Sir Clement Clerke and his son Talbot, using reverberatory furnaces. However, her husband and her partner in the enterprise, Lord Grandison, were suspicious of the Clerkes. The result that the enterprise was the subject of litigation, which continued until after Henry Howard inherited the earldom with its associated estates. He seems then to have stopped contesting the litigation, which was decided in favour of the Clerkes.
