Various old documents may here be quoted, which give items of interest connected with this church. In _Lincolnshire Wills_, 1st series, edited by Canon A. R. Maddison, F.S.A., 1888, is that of James Burton of Horncastle, of date 9 June, 1536, which mentions the lights burnt in the church at that time before different shrines; these were in all 23, of which 7 were in honour of the blessed virgin, one was called “The light of our Lady of Grace,” another “Our Lady’s light at the font.” Mention is also made of a “St. Trunyan’s light;” this last saint is connected with a well at Barton-on-Humber, but nothing further is known of him under that name. It has been suggested that it is a corruption of St. Ninian (_Lincs. Notes & Queries_, vol. i, 149), and in connection with this it is interesting to refer to the fact that Gervase Holles, whose description of Horncastle windows we have already quoted, states that there was a window to St. Ninian placed in the chancel south aisle, by the Guild of Shoemakers. Here, then, it is possible, the “St. Trunion’s” or St. Ninian’s “light” may have been burned, as the emblem of some whilom Horncastrian’s faith. A Chancery Inquisition post mortem, 19 Richard II., No. 83 (11 Dec., 1395), shows that Albinus de Enderby and others assigned a messuage, with appurtenances, in Horncastle, to pay a chaplain to say daily masses in the church of the blessed Mary, for the soul of Simon de Dowode, and other faithful deceased. Wood Enderby was at that time a chapelry attached to Horncastle Church.
