According to Encyclopedia, the name "Tietjen" originates from the name "Dietrich".'s Erstmal so I accepted ... until I leave the Normandy had been in once. Where is called the "Dietrich" ==> Didier. So what if one the phonetically pronounce it really is no further away to the name "Tietjen." Finally, I would like to say that this statement is a pure hypothesis on my part. But maybe someone has quellenbezoegene information.
