Account of rents and profits due to Piers Griffith of Penrhyn for messuages and lands in Maenol Bangor, Cororion and Llanllechid, Bangor lists of very great interest; so are the Llanllechid entries, such as Ty yn y Twre [Ty 'ntwr], and Ty Gwynn in Llanfranken [Nant Ffrancon]; and the reference under "Ladies jointure (sic)" to £6 for Cilgeraint and the "quarie of slates ther[e]". No date, but circa 1610. c. 1610
