Aurora and Natali
From Quasi-Modo.com:
"June 23, 1914, Fort Wayne, Indiana: Children’s Playground association festival; entertainment provided by Con. T. Kennedy shows; "The side show tents are always full. Many strange and interesting people and curiosities are presented, chief among which are the Aztec women, Aurora and Natalia, these strange little creatures are unfailingly attractive in young and old."
Aurora and Natali's manager was Max Klass. They traveled with the Sells-Floto Circus Sideshow in 1910.
There is some debate whether they grew up to be Schlitzie and Athelia.
