1) Progenitor: the oldest DNA mother in a family who came to SA. (Will incl women who only had daughters, but also Daan's Ouma Wiese - who wasn't married to the SV)
2) In the cases where this means that the wife of the SV is not acknowledged as the Matriarch of his Surname Line of male descendants, then, I suggest we add a profile image that acknowledges her as the SM/Matriarch (Moved the SM name here, to fit with Daan's point that this is the definition of an SM in SA genealogy tradition, and not the 'oldest mother = Prog one.)
3) If she is both the oldest mother and married to an SV then she is SV/PROG (old image)
