On Iv the s. 15 inscription 'Iste liber est de comunitate fratrum minorum Babwell' ex dono fratris Willelmi Hylton pro anima fratris Iohannis Hylton magistri'. For John Hilton, Franciscan Friar (who died at Norwich, 1376), see Emden, BRVO II, 9367. Other s. 15 inscriptions are: (Iv) 'Iste est liber fratrum Willelmi Hilton' et (...)
