From Welsh Biography Online (http://yba.llgc.org.uk/en/s1-GRIF-PEN-1300.html) :

"GRIFFITH OF PENRHYN (Caerns.) . The family was perhaps the first in North Wales to emerge as the owners of a modern landed estate. They claimed descent from Ednyfed Fychan (q.v.) through his son Tudur .
...
The patrimony of Tudur ab Ednyfed Fychan undoubtedly lay in the Four Cantrefs, and record evidence supports the testimony of the pedigrees that his descendants, in the line whence came the families of Griffith of Penrhyn and Williams of Cochwillan , were settled at Nant, in Englefield, and Llangynhafal, in the vale of Clwyd. So far from being settled at Penrhyn early in the 14th cent., the 'Griffith' family continued to live in north-east Wales until the close of the century; but three marriage alliances during the century brought them substantial property in Caernarvonshire and Anglesey."

Tudor married Adlais verch Richard ap Cadwaladr, daughter of Richard ap Cadwaladr and Unknown.
