Wally as a feminine name represents an uncommon usage of what is traditionally a masculine nickname. Typically, Wally serves as a diminutive of Walter (meaning 'ruler of the army') or Wallace ('Welshman' or 'foreigner'). For girls, it occasionally functions as a nickname for names like Wallis or Walburga. The feminine usage gained some recognition after American socialite Wallis Simpson, for whom King Edward VIII abdicated the British throne. The name has a casual, friendly quality with a somewhat vintage appeal. While never widely popular for girls, Wally offers a tomboyish option that contrasts with more traditionally feminine names. Its rarity as a feminine name makes it distinctive, appealing to parents seeking uncommon gender-neutral options with historical connections.
