Television viewers of a certain age (well, candidly, old Americans) may remember The Patty Duke show from the 60s. The premise was that the daughters of identical twin brothers were, well, identical cousins. https://youtu.be/qQTqKcojrVY MICrowe Audrey and MOCrowe Ellie aren't quite identical, although Audrey's mother bought them matching dresses. They are almost exactly two years apart in age but Ellie is only a little taller and they are the best of friends. They favor the same hairstyle. Here they are patiently waiting to board the Ferris wheel on the roof of the City Museum.
