Anna was often assigned by George John to act as mediator in his business affairs: in 1588, she was given the task by him to persuade Charles III, Duke of Lorraine to prolong his chance to buy back the city of Pfalzburg, which he had previously sold to Lorraine with the right to buy it back, so that he might have the time to loan money to buy it back in time.[1] Anna successfully persuaded the Duke of Lorraine to prolong George John's right to buy Pfalzburg back, but it finally became a part of Lorraine in 1590.[3]
