While her rank and nationality are unknown, what proved significant was that in English society she was not considered a suitable spouse for an earl.
[2] Agnes accompanied Anne of Bohemia, the future consort of King Richard II to England in December 1381.
She served in the capacity of Lady of the Bedchamber, and was also the custodian of the jewels and valuables given to Queen Anne by her mother, Elizabeth of Pomerania.
On an unknown date, Agnes caught the eye of the King's favourite, Robert de Vere, 9th Earl of Oxford, Marquess of Dublin, Duke of Ireland.
This created a scandal throughout the kingdom, especially as Philippa was the first cousin of the King, being the youngest daughter of his aunt, Isabella of England.
The second version is that Queen Anne, through genuine fondness for Agnes, wrote to the Pope, urging him to grant the divorce.
