Here me out: this is Adrien's mom. Remember the scene where Adrien went behind her painting. Remember the peacock pin? I bet that was her miraculous. And his father is obviously Hawkmoth. So maybe they had a similar story to Marinette and Adrien, yet when his mom died (did she?) his father was too heartbroken, and then began to use his powers for bad. Why has no one thought of this? Like seriously I knew it as soon as I saw the pin.
