The Killigrew Baronetcy, of Arwennick in the County of Cornwall, was a title in the Baronetage of England. It was created on 22 December 1660 for William Killigrew (d.1665), 6th son of John Killigrew (c.1557-1605) of Arwenack, near Falmouth in Cornwall, thrice MP for Penryn in 1584, 1586 and 1597, and Vice-Admiral of Cornwall and like his father and grandfather was Captain of Pendennis Castle (1584–98)[1] The 1st Baronet was created a baronet at the Restoration of the Monarchy in 1660, which event was largely brought about by his uncle George Monck, 1st Duke of Albemarle (1608-1670). He died without progeny and the title by special remainder descended to his nephew Peter Killigrew, son of his elder brother Sir Peter Killigrew (1593-1667), MP for Camelford.[2] The second Baronet was Member of Parliament for Camelford. The title became extinct on his death in 1704.[3] [4] [5]
