The Millie-Christine sisters, conjoined twins, standing. Photograph, c. 1871.

The "Millie-Christine Sisters", also known as the "United African Twins", were exhibited by a Mr. Jos. P. Smith accross America for the first 9 of their 10 years. They were "stolen" by another showman and moved back and forth accross the state lines, singing patriotic songs, then finally to England where their original "owner" won them back in court. The sisters died, Millie following Christine, in October 1912
