Abraham Mignon
Marrel's stepdaughter Maria Sibylla Merian (1647–1717), daughter of the engraver Matthew Merian, who lived with Marrel and thus studied with Mignon, achieved distinction as a flower painter. Besides Merian, his other pupil was Ernst Stuven. He left two daughters when he died; Catharina and Anna.
Sibylla of Anhalt
Sibylla was born in Bernburg in 1564. In 1577, her elder sister Anna Maria was relieved from her post as Imperial abbess of Gernrode and Frose in order to marry Joachim Frederick, eldest son and heir of the duke of Brieg; under pressure from her father, the Chapter elected Sibylla as her successor. Sibylla was confirmed in office by the emperor, Rudolph II. During her reign as abbess the only record of her activities comes from an abbey document in which she invests the widow of Stefan Molitor (the first Evangelical Superintendent of the abbey) with a piece of land.
