Authun: Either this has been corrected in the meantime (I am writing on Nov 11 2009), or your observation is not accurate, for there is but one reference to Etta and it does not make a claim either way as to his fatherhood. 

 ==Proper Name== 
 As of my writing this (Nov 2009), the article refers to the subject as Rudolf Wanderone, and that his surname was originally spelled "Wanderon". However, a stop by FindAGrave (a link to add) refers to him as Rudolph Walter Wonderon, Jr. A plate marking his grave bears the name Wonderon. Are "Rudolph" and, especially, "Wonderon" alternative valid names to consider referring to somewhere in the article?
