After months of research, and calculations. I have cross referenced her voice, her mother's voice, and many male voices, I have also cross referenced her looks, her likeness, and her personality.
I have seen that for years people have debated who Dawn's father was. After months of research I finally found out the one person that could be Dawn's father. I used a number system of 10's and 5's and this man, Dawn's father matched up to 100 percent of being Dawn's father, no doubt about it. I first used Dawns head shape, as well as her mother's and have found the man who has the exact head shape. I then calculated her voice. I cross referenced over 150 people, only two matched up. I quickly was able to disprove one of them, leaving the one man, Dawn's father left. I also referenced the way she dresses. Casual. Only one other man dresses in casual. I also cross referenced her age, she was born 27/28 of September, and the year was 1996. Making her the age of 15. Only one other person matched up with this.
