Narcissus Marsh (20 December 1638 – 2 November 1713) was an influential English clergyman and scholar who held key positions in the Church of Ireland. He served as the 13th Provost of Trinity College Dublin and made significant contributions to the study of the Irish language. Additionally, Marsh played a pivotal role in the establishment of the Dublin Philosophical Society and was a notable figure in the scientific community, coining the word "microphone" from Greek roots. Throughout his career, he held several key positions, including Archbishop of Cashel, Archbishop of Dublin, and Archbishop of Armagh, leaving a lasting legacy. Marsh's contributions extended beyond religion and academia, as he also founded Marsh's Library in Dublin and left a valuable collection of oriental manuscripts. His remarkable life and work continue to be remembered and studied to this day.

Narcissus Luttrell (1657–1732) was an English historian, diarist, and bibliographer, known for his comprehensive documentation of the Parliaments of England and Great Britain. His diary, eventually distilled into the book "A Brief Historical Relation of State Affairs from September 1678 to April 1714," offers a unique insight into legal, political, and parliamentary matters of the time. Luttrell's meticulous records are considered invaluable, providing crucial political information and shedding light on debates and legislative significance that might have otherwise been lost to history. Additionally, he compiled a bibliography of texts relating to the Popish Plot and owned an impressive book collection. Despite the dispersal of his materials after his death, remnants of his collection are housed in libraries such as the British Library, Beinecke Library, Newberry Library, and Huntington Library. Luttrell's legacy continues to be celebrated through his works and the remnants of his collection, offering a valuable resource for historians and researchers.
