The only data would be baptismal records which one would have to trace back through the generations. South African census returns get pulped as soon as the number-crunchers have crunched!
That said, Afrikaans-speaking South Africans have a history of naming children after older relatives - first son after paternal grandfather, second son after maternal grandfather, then on to the uncles ... and since families used to be very much larger than today and the available name pool was not large, amalgamations like Susara would have been a good way of avoiding two sisters named
Susannah Sara. But that would mean mining countless church records to establish the presence of ancestral Sara(h) and Susanna(h) people. There used to be a good local genealogy website which would have been a go-to source, but it died about a year ago.
The tradition of merged names continues. I know a
Janine who married a
Rudolf and had a daughter named Runine. Give me Susara any day! Though I also had a colleague once who was known as
Sue (she'd married an Englishman) but her given names were Susara
Susannah. Someone asked her if the minister who christened her had a stammer ... but it was another instance of "having to" name her after relatives.
Other familiar mergers are Elizma (
Elizabeth +
Maria) and Marelise (
Maria +
Elizabeth). Once I knew a Marelna whose full names were
Maria Elizabeth Helena; she gave her daughter Marelna as her full name. Jomarie, from
Johanna Maria, is also well known, and pronounced like the English
Joe +
Marie - JOmaREE.
