The Marvel Family is the DC Universe's first superhero family. There have been many members over the years, including Uncle Marvel, Captain Marvel, Jr. and Mary Marvel; but the original group was founded by Captain Marvel and the Lieutenant Marvels.
During the events of 52, Captain Marvel's longtime foe Black Adam would go on to create his own version of the Marvel Family which he called the Black Marvel Family.
In The New 52, the Marvel is now known as the Shazam Family.
The Marvel Family was created by C.C. Beck, first appearing in Whiz Comics #21. (1941)
