Overview
Hedwig is a German feminine given name, from Old High German Hadwig, Hadewig, Haduwig. It is a Germanic name consisting of the two elements hadu "battle, combat" and wig "fight, duel".
The name is on record since the 9th century, with Haduwig, a daughter of Louis the German. The name remained popular in German high nobility during the 10th and 11th centuries.
Other medieval spellings include Hathuwic, Hathewiga, Hadewich, Hadewic, Hathwiga, Hadwich, Hatwig, Hadwig, Hediwig, Hedewiga, Hedewich, Hedewiih, Hatuuih, Hetvic, Haduwich, Hadawich, Hatuwig, etc. Forms such as Hadiwih, Hadewi, etc. suggest that the name is the result of a conflation of two separate names, one with the second element wig "fight", the other with the second element wih "hallowed".
