- You may be looking for Rachel Dawes.
Mrs Dawes was a maid at Wayne Manor, who worked for Thomas Wayne. Her daughter Rachel would often play with Thomas's son Bruce, and one day Mrs Dawes apologized for not keeping an eye on them when Bruce fell down a well in the garden. When the Waynes were murdered, Mrs Dawes stopped working at the house, but she missed the place.
It's unknown if she was widowed or divorced as she was not seen with her husband along with Rachel during Thomas and Martha Wayne's funeral at the time.
After Rachel's death, it is also unknown what happened to her afterwards. She might have presumably went into a deep depression over her daughter's death by the hands of Joker.
