I think we are looking at the problem from the wrong angles (being separate angles). The problem can perhaps easily be solved when we look at all the combinations that are possible (and admitting that nothing is impossible, that we need flexibility). I think you would understand my conclusions better afterwards.
Below: x=nothing (of Sx, PROG or Sx/PROG), males are first, using the existing meanings of the words (that can easily be replaced with others)
Combinations:
SV/PROG-SM/PROG = both progs coming here together, building stam together
SV/PROG-PROG = a SV/PROG marrying a from overseas female prog but they have no children together in his stam with the PROG (this therefore only possible if he has another stam)
SV/PROG-SM = a SV/PROG and a local born female of another stam in RSA, they have stam
SV/PROG-x = a SV/PROG marrying female but not having stam with her
SV-SM/PROG = a younger brother of a sv/prog and a non-local prog female building a stam together
SV-PROG = a younger brother of a sv/prog marrying a non-local prog where she has no stam in any of her relationships
SV-SM = a younger brother of a sv/prog marrying a female of another stam, they building stam together
SV-x = a younger brother of a sv/prog not building a stam with this female
x-SM/PROG = a local male of a stam, marrying some other stam’s SM/PROG
x-PROG = a local male part of an existing stam, marries a female prog, (however, do they need a stam for her to be PROG or must she be PROG of another stam)?
x-SM = a local marrying some other stam’s SM
x-x = run of the mill business
Propose that we rank Sx/PROG above PROG above Sx.
Conclusions:
I think it will be unfair to place a LOWER limit of 2 on the male, but effectively NO limit on the female Easiest should be that once there is a child, a legacy was left, which may or may not be in tact today or in future for that matter.
Also, the definition of stam above unfortunately therefore cannot mean both a male and female version (then all the defs are bogus), needs to be surname (traditionally male) only I would guess, and prefer.
So yes, for males there would be a distinction between SV/PROG and SV (being the oldest), but it has other meaning when distinguishing between SM/PROG and SM. I think what Sharon says is that SM and PROG must be exchanged for the English?
In either case, I suggest that we don’t use PROG for both males and females… and there is perhaps room for another female version of SV that will be equal to the male version, i.e. a younger sister?
That will be my contribution for now, instead of a long document, and what I said previously.
