Sir Leoline, or Lluellin Jenkins, who was born at Llantrissent in Glamorganshire, was the son of an honest, plain countryman, whom Mr. John Aubrey says he knew. As his father's circumstances were but narrow, and he was a distant relation of David Jenkins the famous Welsh judge, that gentleman contributed something towards his education. About the time that he took his batchelor's degree, sir John Aubrey sent for him home to his house at Llantrithied in Glamorganshire, to instruct his eldest son Lewis in grammar learning : he also took several other young gentlemen under his care, whom he taught in the church-house belonging to that place. He went to Oxford, together with his pupils, and afterwards travelled with Mr. Lewis Aubrey. Upon the resignation of Dr. Francis Mansell, which was soon after the Restoration, he was elected principal of Jesus college. He afterwards retired to London, and was made a judge of the admiralty, and of the prerogative court. In 1669, he was sent ambassador to France; and, in 1673, was sent to Cologn, in quality of plenipotentiary, together with the earl of Arlington and sir Joseph Williamson. In 1675, he was appointed a plenipotentiary at Nimeguen, together with lord Berkeley and sir William Temple; and, in 1680, he succeeded Mr. Henry Coventry in the office of secretary of state. He is said to have preserved the leather breeches which he wore to Oxford, as a memorial of his good fortune in the world. Ob. 1 Sept. 1685, Ætat. 62.
