Posthumus

Posthumus is a surname mostly stemming from the Dutch province of Friesland. Among variants are "Posthuma" and "Postmus". The surname may have originated in the same way Romans called boys and girls born after the death of their father "Postumus" and "Postuma", and the common Frisian name Postma sometimes is a derivative of such a name. Alternatively, the situation is reversed, with the surname "Postma" or "Postema" morphing to "Posthuma" and further to "Posthumus". People with this surname include:
