How JKR got Voldemort’s Name (?)

Has anyone come across the Edgar Allan Poe short story called, "THE 
FACTS IN THE CASE OF M. VALDEMAR" 

http://www.sff.net/people/DoyleMacdonald/l_valdem.htm  

It is just like JKR to refer to the writings of some of her favourite 
authors in creating character names.

Valdemar was near death, but prolonged his life is a way that scared 
or sickened medical staff. 

What do you think?  ~aussie~

PS. I found this story in from a different source, so I haven't been 
through the other stories in that web site's "library". Good luck 
finding any other clues to character names
