The Karak dynasty
Kim is a common surname in Korea and King Kim Suro is considered to be the father of the Kim clan which is based in Gimhae.
“While traditionally children in Korea take their father’s surname, the queen is said to have been sad that her children could not bear her surname,” says Minji Lee of the BBC Korean Service.
“The legend says that therefore King Suro allowed two of their sons to take her name (Heo), which is used to this day.”
Today, historians say, descendants of the couple number more than six million, which is roughly about 10% of the South Korean population.
People from the Karak dynasty have also preserved the rocks that are said to have been used by the princess during her sea voyage to Korea to keep her boat stable.
Former South Korean president Kim Dae-jung and former prime minister Kim Jong-pil claim their ancestry to the Karak dynasty.
