Due to how she and her twin brother were conceived, they weren't immediately allowed to inherit the Count title or property from their supposed father, Roger Kameny. Anna and her children ended up going through three trials before her children were allowed to bear the title and inherit Roger's estate. Unlike her brother, she was ok with this and didn't push to be recognized as Amavet's daughter.
Her wealth, combined with her beauty, meant Muriel had no trouble finding a husband, despite the rumors about her being an illegitimate child and, at age 17, she married Robert of Garramone. The couple had two children together, Robert II and Adalia, before she was widowed at 24 years old when Robert was killed during a battle with Aedirn. Later on she married the Count de Ruyter, making her Countess de Ruyter, and the couple had three daughters: Jolanta, Julia, and Joanna. She passed away at 64 years old.
