In the Mahabharata, Dushala (the only daughter of Dhritarashtra and Gandhari) was married to Jayadratha, the king of Sindhu. Jayadratha later played a crucial role in the Kurukshetra war, leading to his death at Arjuna's hands. Karna was married to Duryodhana's wife's sister, Shalya was Nakula and Sahadeva's maternal uncle, and Jarasandha was a king of Magadha.
