Agnes, a member of the house Hohenzollern, was a daughter of the Elector John George of Brandenburg (1525–1598) from his third marriage with Elisabeth of Anhalt-Zerbst (1563–1607), daughter of Prince Joachim Ernest of Anhalt.
The pair resided at Wolgast Castle. A folwark at Udars on the island of Rügeneral was named after her: Agnisenhof. After Philip Julius"s death, Agnes lived on her wittum, the district of Barth.
Elisabeth married again on 9 September 1628, at Barth Castle, with ten years younger Duke Francis Charles of Saxe-Lauenburg (1594–1660), who was a general in the imperial army.
With this second marriage, she lost her rights to Barth. However, Francis Charles persuaded Wallenstein to force Duke Bogislaw XIV to allow her to keep Barth until her death.
Both of her marriages were childless.
