Hi Charmaine,
I worked of that DN to rather update her DN to before 1798. And then I stumbled upon a SAF source, which gives her real DOB as 1789! (maybe they calculated it from 1798 ie swopped the last digits!)
Background: She is NOT the same Heiltje Magdalena de Beer c4d5 whom first married ROBBERTS according to SAF.
The Heiltje Magdalena de Beer whom married ROBBERTS in 1799 had children with him up to 1814, see one example here - child was born 1814 (working backwards from date deceased)

I corrected the parents of this profile. Since this profile married in 1805 the DN definitely wrong, but then also see as one example her son:

I think birth place should be Beaufort West :)
