Anglo-Saxon boundary clauses are descriptions in Old English (and sometimes Latin) of the boundaries of land-units recorded in charters dating from the seventh to the eleventh centuries. They are typically in written form, and walk the reader clockwise around the perimeter of the estate or territory, citing features that the boundary passes, crosses or follows. This paper, delivered at the Association's July 1876 Ashburton meeting presents and comments on a Devon-boundary-related manuscript from the time of Edward the Confessor (first half of the 11th century). Its Appendix in particular, is a treasure chest of Devon landholder names of the period. Google with the Archive Organization has sponsored the digitisation of books from several libraries.
