Do some people still have old Latin names and surnames?

Translating your surname into Latin was in fashion in the 16th through 18th centuries for many Germans and Swedes; Linnaeus (von Linné), for example, or Neander (as in Neanderthal; Neumann).

EDIT: Philip Newton points out Neander is Greek. True dat. OK, try Faber (surname), Latin for “Smith”. Or Schmidt.

Sometimes, it has stuck around. I’m assuming Oscar Pistorius is also an instance of Afrikaaners doing this.

See Why are some old German surnames Latin?

I can think of other examples of Latin surnames in Germany, such as Michael Praetorius. There was even a good footballer in the 80’s named Holger Hieronymus.
