Pretorius

Pretorius is a common Afrikaans surname.
Recorded in several forms (including "Praetor", "Praetorius", "Pratorius", "Pretorius", (German), and in English "Preater", "Preter" and "Pretor"), Pretorius is a surname of Germanic origins, although the ultimate origin is the Roman (Latin) word "praetor". This literally meant "leader", but was used in Imperial Rome to describe officials who led processions, as well as the Praetorian Guard, who provided the security for the Senate and the Imperial Roman family. Although apparently first recorded in England several centuries before Germany, which is probably because of lost medieval records, it is rare in England, although now found in some numbers in Austria, Switzerland and South Africa.
