Benjamin Schaefer's family - his siblings and parentage

Benjamin Schaefer was the ninth of ten children born to Carolina Wilhelmina SCHAEFER nee KRANTZ. With her first husband, Johann SCHIEDER, Carolina had five - or possibly six - children. According to records on familysearch.org, Carolina and Johann DIVORCED in Bethulie, Orange Free State around 1880/1881. Here is Carolina and Michael's wedding certificate (in Afrikaans):

Shortly after the divorce, her sixth child - Carolina Louisa - was born. On her baptismal entry, no father is named, but she is baptised Carolina Louisa SCHIEDER (see pic, below); however, 7 months after her birth, her mother remarries Michael SCHAEFER. 

On her own wedding certificate (and in her parents' death notices) Carolina Louisa SCHIEDER is named as Carolina Louisa SCHAEFER. It seems michael may or may not have been her father; either way, he raised her as his own and she took his name.

I can find no trace of Johann SCHIEDER after the baptism of the fifth child, Annie Margaret SCHIEDER, in 1878; did he die? Did they divorce? Did he run off and leave Carolina Wilhelmina? Johann (known as John) was a butcher, and their children are baptised with the parents named as 'John and Caroline SCHIEDER'.

Curiously, there is a baptismal entry for a child of John and Caroline named Franz Heinrich SCHIEDER, born 7.5.1876. He is not mentioned in the parental Death Notices as ever existing; perhaps he died in infancy. Also, a child of a similar age IS named in the Death Notice but I cannot find a baptism record for him; perhaps they are one and the same? Franz Heinrich = William Antonie?

Another curious baptismal entry (pic) is that of Anthony William Richard SCHIEDER to John and Caroline on 16.11.1873. He went on to marry Elizabeth Catherine Pretorius. Scandalously, he is documented as spending two years in Jail sentenced to 'Hard Labour' for being a thief. In 1901 it is documented that he requested 'early release, because of the Coronation'. He is NOT listed as a child of Carolina Wilhelmina on her Death Notice. Was he disowned by the family? He died in 1924.

Here are the Death Notices for Carolina Wilhelmina SCHAEFER and Michael SCHAEFER:

The 'Antonie' middle name seems to come from the father -Johann's full name is once recorded as John Anton Michael SCHIEDER.

Caroline Wilhelmina KRANTZ - SCHIEDER - SCHAEFER seems to have been something of a character; working as a butcher with Johann, bearing 5 or 6 children with him, divorcing, remarrying pretty quickly, and working as a blacksmith alongside second husband Michael SCHAEFER in Joubert Street, Bethulie. Oh, and bearing 4 more children, one of which was Benjamin. An interesting life!
