Thanks to Martin Andreas Karl (Dries) Potgieter having uploaded his genetic test result, we can now be pretty sure that the SA POTGIETER Progenitor was of the Y DNA Haplogroup R CTS 8401 (R1a1a1b1a3b1).
Which looks to me to be the Haplogroup of a lot of Swedish people, although (Roland Henry Baker, III &
Private User can comment on my 'quick & dirty' internet search findings :-))
So great of you to share this, Dries. That means that any other male Potgieters on Geni are likely to share this Haplogroup- because Y-DNA is passed from father to son to son to son etc. [ie even though Harmen Jansz Potgieter is my 9th gr grandfather, neither I nor any of my brothers will share his Y-DNA. (Me, because -as a female- I don't have Y-DNA :-) My brothers because he is not a direct patrilineal (fatherline) grandpa - there are grannies inbetween.)]
