Hanyang Han
The Hanyang Han were a Goryeo aristocratic clan of Hanyang, present-day Seoul. They branched from the Cheongju Han: their founder Han Won-seo, a sixth-generation descendant of Cheongju founder Han Ran, passed the civil examination under King Chungnyeol (r. 1274—1308), rose to high office and was enfeoffed as Prince of Hanyang, after which his descendants made Hanyang their clan seat.
