Dillon is a gender-neutral name of Irish origin, “loyal” or faithful." This 12th-century surname was introduced to Ireland during the Anglo-Norman invasion at the time, which is also responsible for its French roots and alternative meaning of "lion." It has since evolved into a reliable first name with many diverse spelling variations, including Dylon, Dilon, and Dillen. Although Dillon and Dylan share the same pronunciation, they have separate origins, with Dylan originating in Wales and meaning “sea.” If you’re looking for a unique take on the popular classic Dylan, Dillon and its related monikers will be an excellent choice for baby.
