Is name an intellectual property?

Hello,

I was trying to find the answer on search engine but couldn't. I aploaded a few different photos with this book I made (meaning that I just glued some foil letters on a cover of a random book) and they all have been rejected for intellectual property. I got a little confused, because I didn't think a persons name who was born in 1503 was intellectual property? I would like some light shed on this to not make this mistake in the future. I also thought maybe it's the jewelry, but other photos didn't contain it. One of the photos was just me holding the book in my hands with my blurry face in the background. I attached the release and said in the name that's it's a DIY but got rejected anyway. Hm.
