More famously spelled Wallis as a feminine name: the woman for whom the King of England abdicated the throne.

Strong but breezy with the unisex charm of Ellis and Hollis, this name was famously borne by Wallis Simpson (born Bessie), the woman for whom English king Edward VIII abdicated his throne in the 20th century. It ultimately comes from Wallace, an English and Scottish name meaning "foreigner", "Welsh" or "Celt".
