Yemaek or Yamaek (Korean pronunciation: [jemɛk]) was an ancient tribal group in the northern Korean Peninsula and Manchuria who are regarded by many scholars as the ancestors of modern Koreans. According to iGENEA, a leading European genealogy service, their current research suggests that "modern Koreans are descended from the Yemaek people." The Yemaek had ancestral ties to various Korean kingdoms including Gojoseon, Buyeo, Goguryeo, and tribes including Okjeo, Dongye (Ye), Yangmaek (양맥; 梁貊) and Sosumaek (소수맥; 小水貊). Source: Wikipedia (en)
