I believe There to be some serious issues with Douw Gerbrand Steyn
1. The profile is not sourced sufficiently.
2. In particular, a source for the wife is added but that lady is more than 20 years his senior (extremely unlikely for that era).
3. The lady passed away in 1863 when he was barely of marrying age.
4. The children attributed to this couple (on Geni) was born in the 1880s, 20 years after this lady passed away.
Needless to say, MyHeritage stacked with these incorrect profiles.
