The brasses in Mawgan church suffered severely at the restoration in 1860–1. All were taken from their slabs and the slabs destroyed. Some were removed to Lanherne Nunnery, but subsequently transferred to Wardour Castle, where they still remain.

The following account is mainly derived from old rubbings in the collection of the Society of Antiquaries; from E. H. W. Dunkin's Monumental Brasses of Cornwall, 1882; C. S. Gilbert's Historical Survey and Heraldry of Cornwall, 2 vols., 1817–20; H. Haines's Manual of Monumental Brasses, 1861; The Roman Catholic Families of England—Arundell, by J. J. Howard and H. S. Hughes, no date; and M. Stephenson's List of Brasses in the British Isles, 1926.
