About Haman in the Qur'an?

A sheikh told me about how the Qur'an mentioned Haman being the pharaoh's minister and how it was questioned that Muhammad mixed up stories from the bible. Then with the discovery of the Rosetta Stone, hieroglyphics were able to be deciphered and the name Haman was found to be written in hieroglyphics saying he was the pharaoh's chief builder. Obviously, this interested me and I want to research about it, but the only stories I find are on Islamic websites, not that I'm saying Islamic sites aren't credible, but I was thinking that this would be a big deal and would have a lot more information and articles about it, so I am wondering if someone could direct me to maybe a peer reviewed article or what an Egyptologist had to say about this matter?
