What is the meaning of the name Drost and where did it originate? The Meertens Institute, the organization that looks into questions of names, writes:
“A Drost was someone with an important and responsible function working for a monarch, earl or duke. The family name probably gives a very close relationship to a drost: the first person employed by a drost carried the name Drost, or he was an adopted child or a child born out of wedlock. The highly responsible administrator probably did not carry the family name Drost.”

Variances to the name are:
