Persia Woolley

 Persia Woolley was an American author who was best known for her Arthurian trilogy of novels.  She was born in California in 1935 and went to college, studying architecture.  She married  James Woolley,  and began to write novels.  She had 2 daughters, and was a single mother for some time.  She later remarried to a Dr Garvin.  She died in 2017.

I've enjoyed her novels which are based on Guenevere, more than Arthur.  Guenevere is a pagan princess from the North of Britain who marries Arthur and grows to love him but also loves Lancelot.. with whom she has an affair.   But Arthur's sister Morgan who hates him, causes trouble and strife, and Guenevere goes into a convent for the rest of her life.  

Woolley was not British but she was an imaginative and intelligent writer.  She gives a picture of Dark Age Britain with its ethnic mixture of Celts, Romans and Saxons who have been moving into the country.
