Exemplification relating to the prolonged dispute between Piers Griffith of Penrhyn and William Williams of Cochwillan over the lands of Gwern y Go, Y Derlwyn, Rhos y Bigelydd, Gwaen Velogyn and Eithin y Maen in Bodvayo and Cororion The former as plaintiff accused W.W. of forcibly entering the above premises, driving away cattle and sheep, and causing serious damage generally. Then follows in 1587 the order from Great Sessions for a local commission to examine witnesses on five interrogatories. The meeting was held at Bangor (22 November 1587) before Morris Kyffin, esq., and Maurice Griffith of Porthmael, when about 16 witnesses were called in behalf of the plaintiff. All the two commissioners could do was to see that the evidence was carefully drawn up and referred to the Court of Great Sessions. The final decree is not preserved. 13 July 1588
