Andries Jan Daniel is born in the Smithfield District. His first marriage is at Smithfield to Clasina Wilhelmina Jansen from the Burgersdorp district. They have a single child, Andries Jan Daniel, during whose birth Klasina dies. Andries marries again soon after to Christina Sophia Jansen, younger sister of his first wife. Before March 1897, the family moves to the Parys area of the Free State Republic.
During the Anglo Boer War, the family is interned in the Vredefort Road Concentration Camp, where son Jacobus Ockert dies of diarrhoea in one of the miserable bell tents at the age of two years.
Andries is captured on 1 December 1900 at Parys as part of the Kromellenboog Commando (Southern Free State) at which time his address is given as Parys in the heilbron District. He is eventually placed in the Vrederfort Road Concentration Camp on 22 April 1901.
Christina ultimately gives Andries seven children of whom three die young, including two boys named Jacobus Ockert; the name of Andries' maternal grandfather. When she dies in 1908, Andries marries Johanna Barendina Wiese. This was a childless marriage.
One peculiarity of this family genealogy, is that two of the witnesses at the baptism of daughter Heyla Elizabeth bear the exact names and surnames of the baby's grandparents, who are both deceased by that time, namely "Andries Daniel Booyens" and "Heila Elizabeth Oosthuizen". As yet, we have no explanation.
