and for more than sixty years from 1831 his pen was never idle. Coming to London, he found employment in arranging the public records, then kept in St. John's Chapel in the Tower, and about midsummer 1831 he was appointed to a permanent situation in the manuscript department of the British Museum. On 19 Sept. in the same year he married Mary Ann, daughter of John Craig of Mount Florida, Glasgow. His post at the Museum brought him into contact with the leading students of British history and antiquities, and he became a member of several learned societies. After his appointment as a sub-commissioner of the public records in 1834, he worked at the proposed new edition of Rymer's ‘Fœdera,’ and he drew up in 1836 the appendix (vol. E) to Charles Purton Cooper's report on that subject.
In London Stevenson gradually dropped his connection with the presbyterian body, and had his children baptized in the established church. On the death of his eldest son, Robert, on 5 Nov. 1839, he resigned his post on the Record commission, returned to Durham, where he entered the university and became a licentiate in theology in 1841. He was ordained priest by Bishop Maltby. In 1841 he was appointed librarian and keeper of records to the dean and chapter in succession to his old schoolmaster, James Raine, and for the next seven years he was engaged in drawing up a catalogue of the charters and deeds preserved in the treasury. In acknowledgment of his services the university conferred upon him the honorary degree of M.A. He was appointed curate of the parish of St. Giles, Durham, in 1847; and in January 1849 he was instituted to the parish of Leighton Buzzard, Bedfordshire.
In 1856 Stevenson undertook to bring out for the Clarendon Press at Oxford a work which, if completed, would have been of a monumental character. This was a chronological list of English historians of all ages, with a critical account of their works, whether in print or manuscript. Eventually he presented the whole of his collections to Sir Thomas Duffus Hardy [q. v.] for his well-known ‘Descriptive Catalogue of Manuscripts relating to the History of Great Britain and Ireland.’ When many plans for continuing the work of the Record commission had fallen through, Stevenson's representation in 1856 induced the government to undertake in the following year the splendid Rolls Series of historical works, under the title of ‘Chronicles and Memorials of Great Britain and Ireland.’ He was himself appointed one of the editors, and in the prosecution of his researches he visited Paris, Rheims, Chartres, Rouen, and Lille. He resigned his living in 1862, and undertook the work of calendaring at the Public Record Office that William Barclay Turnbull [q. v.] had resigned. His study of the history of the Reformation period led him, like his predecessor, to withdraw from the Anglican communion, and on 24 June 1863 he was received into the Roman catholic church. In consequence of the pressure brought to bear upon him, he resigned his post as calendarer, though he continued to be employed as an editor of the Rolls Series. He retired to Selly Park, near Birmingham, and assisted Canon Estcourt in composing his book on Anglican orders. The historical manuscripts commission opened for him a further field for congenial labour, and he examined and reported upon no fewer than twenty-four manuscript collections in the possession of various corporations or private families.
After the death of his wife (11 July 1869) he entered St. Mary's College, Oscott. In 1872 he was ordained priest by Bishop Ullathorne, and in the same year he not only received from Mr. Gladstone a pension in recognition of his valuable services to historical literature, but was deputed by the government, after consent had been obtained from the pope, to make a detailed examination of the Vatican archives. This task occupied him about four years, and the results of his labours are contained in thirteen folio volumes of transcripts now deposited in the Public Record Office. In November 1877 he entered Roehampton College as a novice of the Society of Jesus. In 1878 his headquarters were at Oxford, and after that, until his decease, he resided in the ‘House of Writers’ at 31 Farm Street, Berkeley Square, London. On 25 March 1885 he was professed of the three vows, and when he was eighty-six years old, the honorary degree of Doctor of Laws was bestowed upon him by the university of St. Andrews. He died at Farm Street on 8 Feb. 1895, and was buried in the cemetery of St. Thomas's Church, Fulham.
