I'm not sure specifically as I haven't read the 'Mr Carson the Real Man novel'. But he could be the main character, perhaps a complex individual with his own set of values, dreams, and flaws.
In 'the express the ernie davis story', Ernie Davis was a football star. He was a man who faced racial discrimination but still managed to achieve great things in football. He was known for his skills on the field and was a symbol of hope and determination for many, especially African - Americans in the world of football.
In this fanfic, Tracy Davis could be an original character created by the author. She might be a witch who has her own story and reasons for being betrothed to Harry.
There could be his best friend, who has been with him through his journey of self - discovery. This friend might be someone who is also part of the same community and understands Carson's feelings and experiences.
Whether Ben Carson's story is true is a complex question. It involves looking at multiple factors such as the reliability of the sources reporting it, his own statements, and independent verification. In some cases, it might be a combination of truth and exaggeration.
