This name gave rise to a wide variety of modern forms which are not obviously connected if the origins of the names are not known: English Derek influenced by Dutch Derrick, Low German Diderik; French T(h)ierry; German Dietrich. Often confused with Theodore. The German vernacular form Dietrich is witnessed between 1074 and 1087 in the place name Dietrichesdorf (UrkStyr 77) and in 1103 in the place name Dietrichstaine (UrkStyr 94a).
