Augustinians were expected to observe strict protocols in contacts with outsiders, to travel only with their abbot's permission and never to sleep alone. One of the problems at Lilleshall was that canons were often forced to undertake expeditions to the outlying estates, outside direct supervision of the abbot. This was much less prevalent at Haughmond, with its more concentrated estates, although it seems there was sometimes a need for canons to stay at Nefyn, where there was a canons' house in the early 14th century. There were also facilities, including chapels, for canons and abbots to stay on some of the granges, including Leebotwood and Beobridge. As the canons were all ordained priests, they could also officiate at chapels in the extra-parochial areas to the west, although secular clergy were appointed as soon as these communities became viable. Eyton traced in detail how the chapel at Knockin evolved, under the abbey's control, into a parish church with a vicar. In the early years there were lay brothers to help in the work of the abbey, but they are never mentioned after 1190. There were, however, numerous paid officials and servants on the premises.
