Perhaps to keep up interest in the siblings, manager Marechal added Jules Adrien Esmilaire from Machlet Moselle, France. The trio then became "Les Colibris Béarnais" (colibri means hummingbird). Denis became "Deniso" and Jules became "Adriens".  In other photos Jules is called the "Noble Adrien Mab". "Mab" is a reference to "Queen Mab" who in Celtic folklore was the queen of the fairies. In fact, there was a little lady who travelled with the Barnum and Bailey circus who was billed as "Queen Mab".

These photos indicate Jules Adrien had a career before teaming up with Les Nains Bearnais. He was billed as "Le Roi de Nains" or "King of the Dwarfs".
