I apologize in advance for embarrassing myself.
(Daisy is on the right and Violet is on the left.)
Daisy and Violet Hilton were conjoined twins joined at the hips and fused at the pelvis. They were a popular act in the US sideshow and vaudeville circuit in the 1920s/1930s.
By the late 1940s/early 1950s, their success faded. Their last appearance was at a drive-in movie theatre where their tour manager promptly abandoned them, forcing them to find work at a grocery store.
They died at age 60, due to the Hong Kong flu. Daisy died first, and then Violet about a week later.
