Current,there is a Hakka(a southeren Chinese branch) DNA project run by Huizegene,there are some N1c1 among them,I personally know one branch of Liu and one branch of Li belong to N1c1,and even star cluster found,very interesting
Hope one day the result of this project will published
Do not forget about homeland of the whole N
But, of course, they can be truly descendants of Hun-nu nomads.
About Hakka... AFAIK, it's southern China. So far from Mongolian steppes... is it possible? More likely Hun-nu descent will be find on the North.
This Jin Midi descendant's homeland is Fujian,but he is N1c1,a haplogroup origined in Mongolia or Siberia,so his family records they came from Mongolia is true,even 2000 years passed,but his Y still existed in many descendats
I don't know the Liu and Li N1c1 carriers descendants of Xiongnu or not,since their family tree is unclear,but it's not a strange thing,a Miao from Guizhou also M178,and Cai et al 2001 found three M178 on Hmong-Daw of Laos,from Mongolia to Laos?Anyway,very cool history
The Li N1c1 matches,in Fujian,Guizhou,Sichuan,Japan,northeast China,inner Mongolia and Mongolia
