Berhthold

Meaning: “bright” + “might”

From Proto-West Germanic *Berhtawald, from *berht (“bright”) + *wald (“might”). Equivalent to berht + walt. Cognate with Old English Beorhtweald. Possible merger with a name containing hold (“loyal, friendly”) as the second element (perhaps compare Old High German Engilhult and Old Saxon Othelhulda), though this identification remains difficult to substantiate with certainty.
