I checked online and it is actually his birth name. He went by Shammgod Wells during school but had to use his birth name in college because of NCAA regulations.
"Often teased for his highly unusual name during childhood, he went by Shammgod Wells (using his mother's maiden name) throughout high school. When he enrolled at Providence, he was informed that he would have to register under his legal name. Since it would have cost $600 to change his legal name to Shammgod Wells, Shammgod stopped using the alias."
