The Oh Family are the leaders of the Ekaterina Branch.
Branch leadership in the Ekaterinas is usually hereditary. Gordon Oh was the leader until Bae Oh ordered him to be assassinated. Because of the death of her husband, Lin Oh was heartbroken and died a few months later. Bae Oh was trialed in The Hague for the murder of his brother because Alistair Oh told the UN about it. Alistair Oh is famous for the invention of the Microwavable Burrito. Leadership of the branch supposedly went to Alistair, but because the Ekaterinas suspect him of sharing his Clues in the Madrigal stronghold, the question of who led the branch remained unanswered. After Trust No One, where Alistair Oh dies from untreated infections, the current branch leader remained unknown until in Doublecross, where Patricia Oh was made leader by Nathaniel Hartford.
