Do Afrikaans given names diverge from Dutch ones? I mean, is it usual for Afrikaans speakers to have an Afrikaans first name (if existing) instead of a Dutch one? For example, are Dutch names like Lodewijk, Matthijs, Martijn conveyed as Lodewyk, Matthys, Martyn? Or Balthazar and Jozef as Balthasar and Josef? I'd like to find some references.
