Wally

Wally is an English given name that originated as a diminutive of Walter, itself derived from the Old High German name Waldhar, composed of the elements wald, meaning rule or power, and hari, meaning army. It has been used as an independent given name since at least the nineteenth century, particularly in English-speaking countries. The name shares its roots with the variants Walt and Wat, as well as the full form Walter and its cognates Gualter and Gauthier.
