From the valley; meadow dweller
Dallys is a modern variant of the Scottish surname Dallas, which likely originates from the Gaelic words 'dail' meaning meadow and 'uais' meaning noble or high. While traditionally a masculine surname-turned-first-name, this spelling variation is used primarily for girls to give it a more contemporary, feminine feel.
