History TangledFamilyTree / LiveActionTV

** ''Series/HouseOfTheDragon'' elaborates on the Targaryens. Due to RoyalInbreeding, the family tree of House Targaryen and House Velaryon gets increasingly convoluted over time. Rhaenyra herself first marries her second cousin Laenor and then her uncle Daemon, who himself first marries his first cousin once removed Laena (the sister of Rhaenyra's first husband). Daemon and Laena have two daughters together, who are then betrothed to Rhaenyra's two sons from her first marriage (who were [[ChocolateBaby actually sired by an unrelated man]], Ser Harwin Strong). The betrothed are simultaneously stepsiblings, first cousins (legally), and third cousins (biologically).

* ''Series/{{NUMB3RS}}'':
** In the Season 3 episode [[Recap/Numb3rsS03E12 "Nine Wives"]], which deals with an {{Expy}} of the FLDS, a family tree diagram found in a suspect's trailer is so convoluted (due to the massive number of marriages each man has, as well as the prevalence of incest within the cult) that Charlie and Amita don't even recognize it as being a family tree. They only figure it out after Millie initially mistakes it for a ''cattle-breeding chart'' (which is close enough to "family tree" for Charlie and Amita to finally make the connection). Later in the episode, a mother and daughter at the center of the case are [[spoiler:revealed to also be half-sisters; the father married one of his older daughters and had a child with her]].
--->'''Millie:''' (''following a particular line'') For example, this guy married his brother's third wife's second daughter. Ugh!

** Henry, in spades. His mom is Emma. His dad is [[spoiler:Baelfire, Rumplestiltskin's son]]. His grandparents are Snow White, Prince Charming, and [[spoiler:Rumplestiltskin and his late wife Milah]]. He has five sets of great-grandparents: two from Charming (his birth mother Ruth and her husband, Robert; and his adoptive father King George and his wife), one and a half from Snow White (her birth parents are King Leopold and Queen Eva, and Leopold's second wife, Henry's step-great-grandmother: Regina, who is also his adoptive mother, thus making Henry his own great-uncle), [[spoiler:Rumple's parents (Malcom/Peter Pan and Fiona/The Black Fairy)]], and Milah's unidentified parents.

** There's also Charming's late twin brother James, Regina's mother Cora (the Queen of Hearts) and father Henry; and [[spoiler:Henry's adopted aunt, Regina's long-lost half-sister Zelena, AKA the Wicked Witch of the West]]. And since [[spoiler:the immortal Rumpelstiltskin]] apparently had [[MerlinAndNimue a mentor with benefits relationship]] with Regina's mother, Cora, leading to some speculation that ''he'' is Regina's father... Charming hangs a big, fat lampshade on the mess by saying it's a good thing the Fairy Tale culture doesn't have Thanksgiving--because that dinner would be awkward as hell.
** [[spoiler:The end of Season 3 adds Henry's newborn uncle Neal, the son of Charming and Snow White, and Rumpel's second wife Belle and HER parents, Sir Maurice/Moe French and Collette, to the mix.]]

--->'''Milah:''' You've been with my former lover...''and my son?''

* ''Series/TheLordOfTheRingsTheRingsOfPower'': Subverted at first. The horse-riding Numenorians with their elaborated armors defeat the Hordes of Orcs in the Battle of Tirharad with ease. Than it gets DoubleSubverted when Waldreg executes Adar's secret plan of provoking Orodruin's eruption. The Orcs win and the Numenorians retreat back home.

* The Vampire Diaries Universe has quite a few weird relations through marriages and adoptions. Some of the most interesting ones are Elena being stepsisters with Caroline and Alaric's children and Davina being both Hope's aunt (through marriage to Kol) and niece (through being Marcel's adopted daughter, who himself is Hope's adopted brother)

*** It doesn't even scratch the surface on the former royal house, the Targaryens, who frequently (but not exclusively) practiced BrotherSisterIncest by custom. Complicating matters was that King Robert Baratheon, Queen Cersei's husband and the legal father of her three children by Jaime, was a cousin to said Targaryens; and Jon Snow was raised by Lord Ned Stark as his bastard son alongside his legitimate children [[spoiler:(but, in reality, [[FamilyRelationshipSwitcheroo was actually the son of his sister]] Lyanna Stark by Prince Rhaegar Targaryen)]].
