Last year a guy with the name FrankN posted this:

The Sorsum sample additionally suggests a sizeable WHG/SHG component in the TRB Tiefstichkeramik sphere that isn’t fully represented by the Gökhem samples, and most likely represents Swifterband-Erteboelle adstrate. In summary, TRB-Tiefstichkeramik may represent the fusion of both of the EEF streams (Mediterranean/Cardial, and Danubian/LBK, including their differing HG substrate), with North European post-Kongemose HG traditions.
Sadly enough the reaction is not possible any longer.....I like to connect with him (may be a member here? or anyone who knows him?)


OF COURSE OTHERS are invited to react too....


This is my response:
The TRB-West posting is a fascinating posting. Especially for me. My mother’s auDNA is only Hondsrug Drenthe. And as you know this is aTRB West hotspot!


And when I analyse my mothers auDNA I get even for someone with North Dutch ancestry always (in eery PCA, admixture etc) a relative high HG (and sometimes somewhat enhanced EEF). Is this a late echo of TRB West? Or?


These models are based on G25 Eurogenes. My mother is EBG (LB is me and JB my father, he is more generic North Dutch):

From the text:
More plausible, however, is a sizeable SHG element picked up in the SW Baltic Sea area, from where the Tiefstich expansion originated (and from where we unfortunately don’t have any aDNA, neither Erteboelle nor TRB, so far).

Mother has definately a NE European touch.
