What Is the Beyonder's Real Name ?

I was hopping somebody can tell me what the Beyonder's real name is ? I just found out that he is a Inhuman/Mutant... "The Beyonder is the most powerful being of the main comic's universe. The Beyonder was also a mutant. Exposure of his mutant genes to Terrigen Mists had created an unprecedented reaction, bestowing upon him seemingly godlike abilities and granted him amazing power and knowledge beyond all other Inhumans of his time." So he should have a real name ?

I actually just read Secret Wars and Secret Wars II within the past few weeks. I prefer his origin (or lack thereof) in those rather than the retcons they did on him. That doesn't answer your question at all, but I just felt like sharing (and it gives you a bump anyways).

I think his name is just the beyonder

He probably has many names but I know that he went by Frank at one time during his existence on Earth. It was in Secret Wars II I think. :)
