"Louise L." was born in 1869, one year after the famed four-legged woman Myrtle Corbin. Hers was a case of dipygus parasiticus; attached to her pelvis she had the atrophied lower half of a parasitic twin. She had some passive motion of the parasite, but the joints were ankylosed and immobile. Two vestigial breasts were attached near the junction of the twin with Louise's body. She could feel where the twin was touched, except for in its feet. She was married and had two daughters.
According to the Bernard L. Kobel catalog of sideshow images, Louise was also exhibited as Camille de Monville.
