The Rerum contained a note that James Abbes was burned at Bury St Edmunds on 2 August 1555 (p. 510). The entire account of Abbes appeared in the 1563 edition and it was based partly on copies of official documents (which survive) and on personal testimony. There were no changes to this account in the subsequent editions.

The Rerum has a note that Denley, exaggeratedly described as being of noble family ('genere nobilis'), was burned at Uxbridge on 2 August 1555 (p. 510). There is also a version of the articles objected against Denley and Newman together with their answers (pp. 510-13). This is followed by a reiterated mention of Denley's death at Uxbridge and a statement that Newman was burned in September (actually it was 31 August 1555) in Saffron Walden (p. 513). Finally, Foxe stated that he would later print Newman's confession of faith (p. 513). He would print this confession offaith in the 1563 edition but not in the Rerum.

In the 1563 edition, all of the material Foxe would ever have on Denley and Patingham was present, badly arranged. Tyrrell's letter, Newman's confession of faith and a letter from Denley to Simpson and Ardley were now printed, along with a somewhat different, and more complete, version of the articles and answers of Denley and Newman (these last almost certainly taken from official records). The desciption of the final examination of the three martyrs, first printed in this edition, may have come from either official records or personal testimony, but the account of Denley's execution was certainly based on personal testimony.

In the 1570 edition all these materials were re-arranged, but Newman's confession of faith and Denley's letter to Simpson and Ardley were dropped. On the other hand, Newman's account of his examinations in Canterbury was added to this edition, together with Foxe's 'notes' breaking Newman's arguments into syllogisms. Foxe must have received this material while the 1570 edition was being printed, as he inserted it in the text over four hundred pages after the account of Newman's martyrdom (1570, pp. 2135-37). No changes were made to this material in the 1576 edition, and Newman's Canterbury examinations were still printed hundreds of pages out of chronological order (1576, pp. 1856-58). In the 1583 edition, Newman's confession of faith was restored. His Canterbury examinations were integrated with the account of his martyrdom. But, through an oversight, these examinations were also reprinted in their old location hundreds of pages later (1583, pp. 1950-51); consequently these examinations were printed twice in the 1583 edition.

Where Foxe obtained this letter is a little mysterious as it would not have been in an ecclesiastical register. It was probably found in Whitehall and given to Foxe by William Cecil. In 1570, Foxe added a marginal note saying that the recipient was Sir Richard Southwell; Foxe must have learned this from whoever gave him this letter.
