South African mtDNA - Female Progenitors lists Engeltje Cornelisz van der Bout as U5a1a.
This is substantiated by Piet Retief Venter in his post (https://www.geni.com/discussions/135293?msg=939666) where he states:
I'm glad you guys find this interesting! My mtDNA haplogroup (and the haplo of Thea de Wet) is U5a1a. We 'inherited' this, via our different maternal lineages, from Engeltje vd Bout. We also did 'paper trail genealogy', back to Engeltje.
Then in another discussion thread (https://www.geni.com/discussions/141585?msg=973518) Piet Retief Venter states:
My 'tuppence worth', as a layman: I am matrilineally descended from Engeltje vd Bout. My mtDNA haplo is U5a1c1, and, barring mutations, this would also have been Engeltje's haplotype.
i.e. in one thread he states it's U5a1a and in another thread he states it's u5a1c1. The landing page of this project states it is U5a1a.
My wife is also a descendant of Anna Maria Jacoba Pelser, b2c3 *1745.
Piet Retief Venter's line comes from her daughter Martha Maria Griesel, b9 *1776, while my wife's line comes from her other daughter Anna Dorothea Griesel, b2 *1764.
My wife's full sequence mtDNA haplogroup is U5a1c1. Can we reach a consensus on this matter and update the project to reflect?
