Recorded in the Saxon period in England as Eadwaćer and Edwaćer, and also as an occupation Ead-wacer (watchman, security-guard). The two elements are Ead-, (inherited) property, implicitly fortune, happiness, status, nobility; and waćer (with ć as as in ćealc, chalk) a variant of wacor, vigilant, watchful, alert.
