Notable Wolofs 

El Hadji Diouf is a Serer, Diouf or Joof cannot be a Wolof. I will help you with more notable Wolofs time permitting.
Also Diop or Jobe is Lebou not Wolof.  Although someone may be brought up in a Wolof culture,[known as Wolofization] in Senegambia it is by the father's name that determines the tribe of a person.  There a lots of notable Wolof people and I will help you with that time permitting.  Don't be discouraged though, keep up the good job.
