Khem generally thought to be Chem is also thought by some to be Ham. Khem is the Egyptian word for Black and associated with Black Land as opposed to the red land of the desert. Khem corresponds to Nome 2 and Letopolis. Akhmim is a corruption of ḫm-mnw, meaning Shrine of Min, via the Demotic form šmn. The existence of a god named Khem was later understood as a faulty reading, but unfortunately it had already been enshrined in books written by E. A. Wallis Budge http://en.wikipedia.org/wiki/Chem Khem or Kem is also the word for black.
