"Blend of Dre and Shaun"
The name Dreshaun is commonly a male name from the "English" origin.
Dreshaun is a modern American formation built from the short element Dre, as in Andre, combined with Shaun. It first appears in United States birth records in 1994, and its structure matches other American names made from a De- or Dre- prefix attached to a familiar given name such as Deshaun and DeShawn. There is no recorded earlier history for it in a documented language.
The pronunciation of Dreshaun is DRAY-shawn.
