Stephan Douglas Jenkins is the Lead singer of Alternative Rock group THIRD EYE BLIND who has done the smash hit "Semi-Charmed kind of Life" He is NOT using the spelling in "STEF-en" or "STuhFahn" but using it as "STEEV-en" just like "STEEV-en with a ph" -Stephen- I guess we're just trying to say we don't want to use "Seven with a T" anymore! Maybe "Steff" is just for the Ladies.
One of Ash Ketchum's rivals in Pokémon: Black and White is named Stephan. A running gag in the series is that his name is constantly pronounced wrong (STEEV-ən instead of SHTE-fahn).
Stephan the Great who ruled Moldavia (present part of East Romania) between 1457-1504, was a great ruler that won 44 churches and monasteries for every battle. He lost only 2 battles in all his great life.
