The Dalrymple baronetcy of High Mark was created on 6 March 1815, in the Baronetage of the United Kingdom, for Hew Whitefoord Dalrymple, eldest son of John Dalrymple and grandson of Sir Hew Dalrymple, 1st Baronet of the 1698 creation. A general in the earlier stages of the Peninsular War, he had been required to retire after his negotiation of the Convention of Cintra; but he went through the subsequent enquiry keeping a promise to Lord Castlereagh not to reveal the full powers he had been given to conclude terms for a French retreat.[1]
This title became extinct on the death of his son Sir Adolphus, 2nd Baronet, on 3 March 1866.[2]
