..seemed a good enough time to talk about who these five women are!
The story of how the daughter thought she was the mother, and what happened to the original Black Canary was eventually revealed in Justice League of America #220 (November, 1983, by Roy Thomas, Chuck Patton, Romeo Tanghal and Pablo Marcos), which turned the issue where she joined the JLA into a Black Canary first appearance.
Mary then worked with Billy and Freddy (Captain Marvel and Captain Marvel, Jr.) as the Marvel Family!
As time passed, Supergirl was adopted by Fred and Edna Danvers, faced a few of Superman's foes like Lex Luthor and friends like Batman and the Legion of Super-Heroes, then Superman revealed Supergirl's presence to the world in Action Comics #285 (February, 1962, by Jerry Siegel and Jim Mooney) as "The World's Greatest Heroine"...and best of all, these issues were all reprinted in giant sized issues of Action Comics.
Of course, this was the Earth-1 Lois Lane (who loved the Earth-1 Superman, who was a member of the JLA). The original, Earth-2 Lois Lane premiered in Action Comics #1 (June, 1938, by Jerry Siegel and Joe Shuster), and that Lois and Clark got married in the 1950s, as later revealed in Action Comics #484 (June, 1978 by Cary Bates, Curt Swan and Joe Giella).
Over the years, the multiple Earths and various Crises weren't kind to the Hawk couple, as Hawkgirl (later Hawkwoman) and her history got more complex.
Still, these were all wonderful heroines!
