From Wikipedia - Llanuwchllyn (http://en.wikipedia.org/wiki/Llanuwchllyn):
Llanuwchllyn is a village in Gwynedd , north Wales , near the southern end of Bala Lake (Llyn Tegid). Its population in the United Kingdom Census 2001 was 834, of which approximately 81% were Welsh-speaking.
Llanuwchllyn railway station is the headquarters of the narrow gauge Bala Lake Railway , centred on the former Great Western Railway station on the standard-gauge line from Ruabon to Barmouth . The town was the birthplace of Welsh language author and educationalist Owen Morgan Edwards . Caer-gai, a Roman fort near Llanuwchllyn, was traditionally known as the home of Cei , the character in the Arthurian legend known in English as Sir Kay. Poets of the 15th century recorded a story, ultimately deriving from the Prose Merlin included in the Lancelot-Grail and the Post-Vulgate Cycle , that King Arthur and Cei were raised at Caer-gai as foster brothers.
Rowland married Sibyl verch Cadwaladr ap Robert, daughter of Cadwaladr ap Robert ap Rhys and Unknown.
