The name probably isn't as important as the display itself, but I think there's a variety of ways to arrive at one. Perhaps there's something meaningful to you that you can take inspiration from? Or if the haunt has a theme, perhaps a name can emerge from that? For instance, if you have a central character, it could be that character's manor, grave, cemetery, chateau, whatever. Anything centered around common themes, such as ghosts, bats, witches, ghouls, etc will work.
Everything I do gets the "NecroBones" label (which in itself is pieced together from things in my past). All of my old business transactions were done under the name "NecroBones Enterprises", so that stuck when I started ordering from Anatomical Chart Co, etc.
Ultimately the choice is yours of course.
