It is extremely doubtful that this was ever a priory in Boston. Alan Rufus granted the church of St Botolph at Boston with lands and a mill dam to St Mary’s Abbey, York. According to G. S. W. Jebb in ‘Memorials of Old Lincolnshire’ (1911), p.120, the grant was made shortly before Alan’s death in 1089 and a priory of monks dependent on York was constituted, the church serving both the parish and priory; in 1851-53, when the church was being restored, foundations of the priory buildings were exposed on the north side; after the sale of the advowson [1490] the priory became unimportant and was dissolved in 1536 (sic). There seems to be no record of a priory at Boston in or after 1291. {1}
