Long dark hair, 200 million followers combined, the youngest descendants of the Kardashian empire, they come up in our newsfeeds every 10 minutes … Yeah, remember them? Dimitrios Kambouris/Getty Images Though we consider the sisters honorary Kardashians, Kendall and Kylie have no blood relation to mama Kris’s first husband Robert. They’re Caitlyn Jenner’s daughters, meaning they are part of an entire other branch of family that we basically never talk about—or at least, not daily. So yes, in addition to half-siblings Kourtney, Kim, Khloé, and Rob, Kendall and Kylie have four Jenner half-siblings: Burt Jenner, Brandon Jenner, Cassandra Marino, and Brody Jenner (see incredibly ‘90s photo of both Jenners and Kardashians below). Donaldson Collection/Getty Images The youngest of the other Jenners, Brody, recently opened up about his little sisters to People. Brody, 34, is marrying fiancée Kaitlynn Carter in Bali in the coming days, and it seems Kendall and Kylie will not be in attendance. “My two little sisters, we never even heard from them,” the groom-to-be explained. “They never even RSVP’d I don’t think.” So we take it they aren’t super close, but like, a text would’ve been cool … ? Scroll down below for a deep dive into the Jenner family tree. Brody, 34 – son to Caitlyn Jenner and Linda Thompson Perhaps the best-known Jenner sibling aside from Kendall and Kylie, Brody burst onto the reality TV scene with The Hills around the same time as America began struggling to keep up with his Kardashian stepsisters. Since graduating from reality programming—which wasn’t that long ago, he hosted short-lived talk show Sex with Brody in 2015—Jenner has followed in the footsteps of many a past-their-prime reality star and now considers himself a DJ. Brandon Jenner, 36 – son to Caitlyn Jenner and Linda Thompson Brandon, a singer (a pretty good one, too!) wed fellow musician Leah Felder in 2012, they share a 2-year-old daughter named Eva James. Before settling down, however, Brandon also dabbled in reality TV—he and Brody starred in 2005 series The Princes of Malibu (for the six episodes it aired), which followed the brothers and then-stepfather David Foster (yes, he’s Bella and Gigi’s stepdad, too!). Cassandra Marino, 37 – daughter to Caitlyn Jenner and Chrystie Scott Stefanie Keenan/Getty Images Cassandra is certainly the most under-the-radar of the Jenner siblings. She and husband Michael Marino share three children together—Francesca, 9, Isabella, 6, and Luke, 20-months. According to the bio on her private Instagram account, she’s “house obsessed” and working on a series of construction projects. Burt Jenner, 39 – son to Caitlyn Jenner and Chrystie Scott Certainly the most out-of-the-box of the Jenners, Burt is a dog-loving race car/truck driver (really!) who cites dad Caitlyn Jenner as one of his biggest career inspirations. He and longtime girlfriend Valerie Pitalo share a 2-year-old son named Bodhi.
