Family Structure: Parents and Full Siblings
Parents and Their Influence
Kris Jenner (formerly Kris Houghton) and Robert Kardashian were married from 1978 to 1991. Their children from this marriage include Kourtney, Kim, and Rob Kardashian. After divorcing, Kris Jenner married television producer Bruce Jenner (now Caitlyn Jenner) in 1991, adding Kendall and Kylie Jenner to the family through that union. As a result, Kim Kardashian and Kylie Jenner are half-sisters through their father’s side and are connected through Kris Jenner as a common parental figure.
Full vs. Half-Sibling Clarification
