The WWE usually loves wrestlers that have a pedigree, and we're not speaking of the Triple H variety.
No, instead we're talking about the legacies of the great wrestling families, such as the Hart's, or the Anoa'i family mentioned by the WWE. Charlotte will never be anything but a Flair following in her dad Ric's enormous footsteps. Randy Orton has always been associated with both his father and grandfather, despite completely eclipsing both in terms of in-ring achievements. Names like Brian Christopher, Ted DiBiase, Curtis Axel all got to where they are with a little help from their famous wrestling families.
WWE aren't the only ones to believe in the power of the family name in wrestling. Smaller promotions like TNA, AEW, RoH, CMLL, Triple-A, and MLW all believe heavily in bringing in 2nd and 3rd generation superstars. Some of the names leading those companies include members of the Blanchard family, the Rhodes family, and members of the Anoa'i family. All of whom have family legacies in the business.
However, most of the big family names are either heavily contracted to WWE, such as Roman Reigns, Randy Orton, and Natalya Neidhart, or have wrestled on WWE TV at some point, from Cody and Dustin Rhodes to Tessa Blanchard's appearances at the Mae Young Classic. Even Teddy Hart and David Hart Smith appeared in WWE- and both were released after failing to live up to their families standards. Cody Rhodes and Dustin Rhodes both made their names with the WWE before they established themselves at the top of the card for All Elite Wrestling.
Some of the names on this list include sons of WWE Hall of Famers, wrestling legends and famous surnames like Von Erich, Hall, and Gunn. Considering that some in this list are third-generation talents, it's a little surprising that they haven't been spotted on WWE TV as of yet.
