They eventually located Millie and Christine while they were on exhibit in Birmingham, England. The law became involved in the situation and, as slavery was illegal in England, the girls were released into the custody of their mother. She, however, had no idea how to proceed with the girls in a foreign country and as a result she gave custody and ‘ownership’ back to Smith.
While Smith continued to exhibit Mille and Christine, he found the public was not very interested. At the time, the anatomical novelty of conjoined twins simply was not enough to capture public attention. Smith decided to develop Millie and Christine as a performing act. Furthermore, he endeavoured to make the girls as extraordinary in skill as they were in appearance. To that end, he and his wife tutored the girls in music and languages. Millie and Christine were taught etiquette, social graces and were given music lessons. It came to pass that the girls developed impressive singing abilities and their singing prowess soon became the focal point of their careers.
As ‘The Two-Headed Nightingale’ the conjoined girls started to gain a remarkable reputation. While Millie was a contralto and Christine a soprano, the girls were able to blend and harmonize their voices in incredibly appealing ways. By 1860, Millie and Christine were on the cusp of stardom.
In 1862 Smith died. The girls were willed to his son Joseph Jr. and it was Joseph who catapulted the girls to stardom by using a clever bit of showmanship.
Throughout much of their life, Millie and Christine were often considered one person. Due to their shared body, it was often unclear if the girls were legally and physically a single being or individuals. The girls themselves often referred to themselves in the singular, using ‘I’ in the place of ‘we’. Joseph Jr. saw opportunity in this confusion and opted to advertise the girls from a new perspective.
The girls became Millie-Christine, a girl with two heads, four arms and four legs.
