The marriage is described as a happy one, and Anna reportedly acted as the adviser of George John, trying to use her influence to restrain his many adventurous and expensive projects.[1] During the journey of her brother Charles in Germany in 1577, he was suspected by their brother John III to conspiring against him, and Anna acted as a mediator.[3] In 1578–79, she also participated in the negotiations between Duke Charles and Maria of Palatinate-Simmern.[3]
