Mathematical Gazetteer of the British Isles

Shirburn Castle, Tetsworth, was the seat of the Parker family, later Earls of Macclesfield. William Jones (1675-1749), originator of the modern usage of π, was tutor to the family here for some years, teaching both the first and second Earls. George Parker (1697-1764), the second Earl, became a noted astronomer. He was the co-author and co-promoter of the 1751 bill for adopting the Gregorian calendar and was then President of the Royal Society in 1752-1764. [1]
