The name Tallis originates from the English occupational surname Talboys, which referred to a maker or seller of tallies, sticks used as counters or measures. The name may also be associated with the famous Elizabethan composer Thomas Tallis (1505-1585). Although traditionally used as a surname, Tallis has recently started appearing more frequently as a unisex given name due to its unique sound and musical connotations. As a given name, Tallis does not have an official meaning but is often associated with the musical heritage of Thomas Tallis. Despite its rich history and distinctive appeal, Tallis remains relatively rare, with only 5 boys named Tallis in the United States in 2019, adding to its attraction for parents seeking unusual names for their children.
