I am writing a history paper on multiculturalism among Philadelphia criminals during prohibition. I came across an online source mentioning an African-American book-keeper named "Forest White Woodard" during this period, and he was said to have become the richest black man in Philadelphia by 1930. However, the only sources I have found about him seem to repeat this phrase and every search I have made regarding him on google has come up empty. Does anyone in r/askhistorians have a scholarly historical article regarding this man's life, or mentioning it in any way that I can use for this paper, or should I omit him because I lack any substantial evidence to discuss him?
