Maad a Sinig Kumba Ndoffene Fa Ndeb Joof should not be confused with Maad a Sinig Kumba Ndoffene Famak Joof, also known as Coumba Ndoffène I, who reigned from 1853 to August 1871. The prefix Famak (or Fa mak) means "the elder" in the Serer language. Fa Ndeb (also :Fandepp, Fa ndepp or Fandeb) means "the young" in Serer. These prefixes were later additions (during and after the reigne of Maad a Sinig Kumba Ndoffene Fa Ndeb) to differentiate the two Kings of Sine who shared the same name and surname.
