Sechten was in Hesse&#45;Kassel, and his father Johann von Siegen became an advisor to the Landgrave, Maurice, who in 1620 appointed him chancellor of the Collegium Mauritaneum, a school for young aristocrats which Siegen attended from 1621 to 1626.
Little is known about Siegen's life between 1629 and 1639, when he asked William V's widow, now Regent for her son William VI, for a position.
