Can anyone tell me the full ancestry.....?

Question

of koreans. like where they first originated from, ect.

Answer 1

My understanding is that they have come from Japanese and Mongolian, but I stand to be corrected. There is an interesting site as below, which discusses the possibilities of Korean origin.

It is one of many. I'm not sure that at this stage anyone can give you the definitive answer, but there are a lot of interesting theories.

Answer 2

A hunter-gatherer culture appeared in the Korean peninsula approximately 40 to 50,000 years ago.  Linguisitic evidence points to the probable origin of Korean culture in Central and Northeast Asia since the Korean language is part of the Altaic family of languages that began on the Monoglian steppe.  

Korean culture quickly absorbed influences from both Manchuria and China: By 300 BCE,  the Yen invasion first brought Chinese culture to Korea.  Korea adopted the Chinese writing system by the 2nd century CE and Buddhism in the 4th century CE while Confucianism became the religion of the Korean aristocracy.

A Mongol invasion brought about the Goryeo Dynasty of the 13th century while a Japanese invasion occasioned the Joseon Dynasty in the 16th century.  In 1910, the Japanese forceably annexed by Japan whereupon Japanese forces occupied Korea until the end of World War II in August 1945.

Answer 3

Technically, your question can't be answered because every korean has a different ancestry.  We are ALL unique. Making generalizations about a certain nation and the heritage of their people is not what genealogy is about.  Genealogy is a very specific science based on documentation of a persons lineage.  Very few people in the world are "full blooded" anything anymore, thus any answer you get would just be an opinion.
