Allow us to shed some light on the very "Brady Bunch" Kardashian family tree: The Kardashians — Kim Kardashian, Kourtney Kardashian, Khloe Kardashian and Rob Kardashian — are children to former O.J. Simpson lawyer Robert Kardashian and Kris Jenner (nee Houghton). She divorced Kardashian and married Caitlyn Jenner, known at the time as Olympian Bruce Jenner. Jenner had sons Brandon Jenner and Brody Jenner from a previous marriage to Linda Thompson. (She also has another son and daughter from her first marriage to Chrystie Crownover.) The Jenners later had two daughters, Kylie and Kendall Jenner, who are also featured on the family's reality TV series. And then there are the love interests and babies.
