Anna was at a plantation when she met "Edward". We truly don't know the name of her husband, so they gave him "Edward" instead. This was an important moment in her life because she ended up marrying him and having kids together.
Anna and her children were sold to Georgia slave traders, except her husband was separated from them. She was taken to a tavern in Washington D.C where she was placed on the third floor.
In the tavern, Anna jumped out of the window as either a suicide attempt or to try and escape. From the jump, she suffered a broken back and fractured arms.
