As a descendant of Rhodri Mawr, Gruffudd ap Cynan was a senior member o f t h e p r i ncely House of Aberffraw.[2][3] Through his mother, Gruffudd h ad c l o s e f amily connections with the Norse settlement around Dublin and h e f r e q u ently used Ireland as a refuge and as a source of troops.[3] He t h r e e t i mes gained the throne of Gwynedd and then lost it again, before r e g a i n ing it once more in 1099 and this time keeping power until his dea t h . G r u ffudd laid the foundations which were built upon by his son Owai n G w y n e dd and his great-grandson Llywelyn the Great.
