The paternal genetic marker of this family was found to be n-mf36689, and the total ancestral time is about 770 years ago
First, the process of finding clues
According to database statistics, it was found that there was a Family surnamed Yan in Shandong and Northeast China. The proportion of male users in this family is 6.67% n-mf36689, which seems not very high, but it is about 74 times the normal level of 0.09% of the type in Shandong.
Statistics found that n-mf36689 is significantly present in the Shandong 'Northeast Yan family, so it is speculated that there may be a Yan family downstream of n-mf36689, and the family members are mainly distributed in Shandong and Northeast China.
Second, through further high-speed testing, do detailed research
In order to further refine, two Yan families in Shandong and Heilongjiang under the n-mf36689 type were selected for "Qualcomm" (also known as depth measurement) refinement.
It was found that both Yan families belonged to downstream branches of the n-mf36689 type. It was divided into 2 branches before 770 years ago (The Song and Yuan Dynasties), corresponding to the Song 'Yuan' era, indicating that there was a certain degree of family reproduction and development at that time. (See figure below)

N-mf36689 This is a descendant of the N1A3 subgenus of the old name of ISOGG
3. Historical knowledge background
So history lovers, when you see this 770-year-old Shandong and Northeast Yan family, what surname do you think of?
Background:
After the overthrow of the Jin Dynasty, the Guanyan family was violently retaliated against and killed. Only a small number of the descendants of the Complete Yan dynasty hid their names and fled to various places. It is said that the surname changed to Wang, Wang, Yan, Jin, etc., and now some of the genealogical descendants of the Completed Yan family have been tested, but the patrilineal y-dye haplotype of the family tree of the Completed Yan in various places is not consistent, and it is difficult to judge which is the true inheritance of the Completed Yan.
Originally, this clue was still too thin, but the contempt for people loved history for many years, boldly predicting that once the right to make history interesting, throw bricks and lead jade. Playing with historical synthesis when there is a lack of information. I hope that everyone will participate together to solve the mystery of history.
In fact, there are also ancient tombs in Guanyan. In Harbin, the tomb of King Qi of Jin Guoqi, whose remains are well preserved, was excavated in Harbin. Finished Yan Yan's father, FinishEd Yan A Clutch, is the uncle of Jin Taizu Completed Yan A Bone. This was originally a very rare research opportunity, both for identifiable ancient remains and for a research institute interested in testing ancient DNA. However, it may be that the matter was closed because the Completed Yan Preservation Unit did not allow molecular anthropologists to take biological samples of ancient remains. It can only rely on more high-throughput sequencing of modern people, combined with family trees to determine the age backwards, and find the end of the face.
