I am seeking the assistance of any person who may be able to assist me in my research of Princess Madryn of Guent, who later lived in the Valency Valley and is said to be buried in the chancel at Minster Church.
I believe there is a stained glass window depicting her in the Tintagel Church. I would be intereted to know the date of that window.
Any information at all would be much appreciated. Although I have visited Cornwall twice, most of my research is done from Australia.
