Evelyn's Diary. 20 Feb 1672. Dr. Parr (age 55), of Camberwell, preached a most pathetic funeral discourse and panegyric at the interment of our late pastor, Dr. Breton (who died on the 18th), on "Happy is the servant whom, when his Lord cometh", etc. This good man, among other expressions, professed that he had never been so touched and concerned at any loss as at this, unless at that of King Charles our martyr, and Archbishop Usher, whose chaplain he had been. Dr. Breton had preached on the 28th and 30th of January: on the Friday, having fasted all day, making his provisionary sermon for the Sunday following, he went well to bed; but was taken suddenly ill and expired before help could come to him.

Evelyn's Diary. 18 Apr 1686. In the afternoone I went to Camberwell [Map] to visit Dr. Parr (age 69). After sermon I accompanied him to his house, where he shew'd me the Life and Letters of the late learned Primate of Armagh (Usher), and among them that letter of Bp. Bramhal's to the Primate, giving notice of the Popish practices to pervert this Nation, by sending an hundred priests into England, who were to conforme themselves to all sectaries and conditions for the more easily dispersing their doctrine amongst us. This letter was the cause of yfc whole impression being seiz'd, upon pretence that it was a political or historical account of things not re lating to theology, tho' it had ben licens'd by ye Bishop; which plainely shew'd what an interest the Papists now had, that a Protestant booke, containing the life and le'tters of so eminent a man, was not to be pub lish'd. There were also many letters to and from most of ye learned persons his correspondents in Europe. The book will, I doubt not, struggle through this unjust impediment. Several Judges were put out, and new complying ones put in.

Evelyn's Diary. 09 Jul 1693. Mr. Tippin, successor of Dr. Parr at Camberwell, preached an excellent sermon.
