From his diary:
October 16, 1646 at 4:30 p.m.
"I was made a Free Mason at Warrington in Lancashire, with Coll: Henry Mainwaring of Karincham in Cheshire. The names of those that were then of the Lodge: Mr. Rich Penket, Warden, Mr. James Collier, Mr. Rich. Sankey, Henry Littler, John Ellam, Rich. Ellam & Hugh Brewer."
His incredible personal collection became the basis for the Ashmolean Museum at Oxford University. Read more about him in Tobias Churton's book, The Magus of Freemasonry.
