I think that the name Nobody was a name Xehanort gave to the body and soul left behind and not the actual name. Nobodies are his servants and in cases abductees. I believe the name comes from the No of No Heart from the anagram Xehanort. Giving a sense of ownership. The thing is that these beings don't know the truth. They are beings that have lost their hearts but unaware that with time they can regrow them back.

Well Xehanort was the one who discovered the nobodies so he named them. Yeah it's the actual name.
