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.
Maria Sibylla Merian
In May 1665, Merian married Marrel's apprentice, Johann Andreas Graff from Nuremberg; his father was a poet and director of the local high school, one of the leading schools in 17th-century Germany. In January 1668, she had her first child, Johanna Helena, and the family moved to Nuremberg in 1670, her husband's home town. While living there, Merian continued painting, working on parchment and linen, and creating designs for embroidery. She also gave drawing lessons to unmarried daughters of wealthy families (her ""Jungferncompaney"", i.e. virgin group), which helped her family financially and increased its social standing. This provided her with access to the finest gardens, maintained by the wealthy and elite, where she could continue collecting and documenting insects. In 1675 Merian was included in Joachim von Sandrart's German Academy. Aside from painting flowers she made copperplate engravings. After attending Sandrart's school she published flower pattern books. In 1678, she gave birth to her second daughter Dorothea Maria.
