In the twelfth century, a Latin Life of her was written by Osbert de Clare, who became prior of Westminster in 1136. According to Osbert, at the age of three, Eadburh was given as an oblate to the Queen Mother Ealhswith's foundation of St Mary's Abbey, Winchester. There Eadburh was educated and there she remained as a nun and died probably before the age of forty. There is little contemporary information for her life, but in a Winchester charter dated 939, she was the beneficiary of land at Droxford in Hampshire granted by her half-brother King Athelstan. According to one account, when Eadburh was three years of age, her father sought an indication as to whether she would live in the world or as a religious. On one side he placed rings and bracelets, on the other a chalice and gospel book. A nurse brought the child, and King Edward set her on his knee, inviting her to choose. When he set her down, she chose the religious items. The hagiography written of her in the 12th century by Osbert of Clare shows evidence of some of the unusual occurrences that might have happened in that time period when a member of a royal family became a monk or nun. In one story, her father visits her in the monastery and she sings for him, and he asks her if there is anything he can do for her, and she asks for him to give the community an estate at Canning, which he does so. In another story, the abbess found her reading alone, which was against the rules of the monastery, and then thrashed her. When the abbess realized it was the princess and not an ordinary nun, the abbess then begged forgiveness from her. In another story, she one time insisted on cleaning the shoes of her well-born companions, and they felt shocked by this and reported it to her father as behaviour that is not right for her.
Veneration
A cult developed after her death and is first mentioned in the Salisbury Psalter from the early 970s. In 972, some of her remains were transferred to Pershore Abbey in Worcestershire, which is dedicated to SS. Mary, Peter and Paul, and Eadburh. Her feast is celebrated on 15 June. Her cultus continued to flourish to judge by the Lives written in the thirteenth and fourteenth centuries.
Dedication of parish churches
There are a number of Church of England parish churches dedicated to St. Eadburh of Winchester. Most of them are not far from Pershore Abbey, to which they were connected in some way.
was at one time co-dedicated to St. Eadburh. Pershore Abbey was also for some time dedicated to her after Egilwado, the nephew of the Abbess of St. Mary's Abbey, acquired some of her bones for £100. The dedication of the Abbey varied at different times in its history. In the Domesday Book it is called the Abbey of St. Mary; in Henry VIII's time the Valor of St. Edburga. It has also been called the Church of SS Mary, Edburga and Holy Cross. In its earlier years SS. Mary, Peter, and Paul were its patron saints, but at the time of the introduction of the Benedictines it was probably dedicated to St. Mary, with whom was joined St. Edburga, whose relics had then not long been added to its treasure.
