Mr Bronson Weir I have updated a few of these profiles' details, including Sarah and her husband's profiles, also adding sources to them. Please take a look at both profiles to see whether you agree. If I made any mistakes please correct them or, if you are unable to, let me know so that I may do so.
I have also seen some baptismal records of which I'm not completely certain, as the same father's forename(s) + surname and the same woman's forename(s) appear on the record, but since there is no maiden name for the mother on the records I cannot be certain that it is the same person. Some of these children's names are also not (yet) on these parents' family tree. Please check the following links and decide for yourself:

One enormous challenge in the South African Tree is that marriages, deaths, and children of indigenous or mixed race were not always officially registered for a large portion of our history (as I have discovered, being of mixed descent myself). Therefore, quite a lot of people were born, got married, and have died without as much as a birth-, marriage- or death certificate.
Something that is most helpful in the case of the Warre/Weir family, is the fact that they were baptized in the Anglican Church which never discriminated on the grounds of race or culture in its record-keeping. All that is required, therefore, is for you to ascertain whether the record applies to the person(s) in question.
