Tensions arose between the Cunninghams and Mures over their rights regarding grazing, etc on the very large and valuable area of common grazing to the north of Polkelly known as Machirnock or Maucharnock, now Glenouther.
It is suggested that tensions had not arisen earlier as previously Polkelly was passed to younger sons of the Mures upon their marriage and this came with an allocation of rights on the moor [REF].
