Catherine of Mecklenburg (1487 – 1561), Duchess of Saxony. 

This lovely lady married Duke Henry the Pious of Saxony in 1512 and had six children. I happen to admire their choice of names for the children: Sibylle (1515-1592), Emilie (1516- 1591), Sidonie (1518-1575), Maurice (1521-1553), Severinus (1522-1533), and Augustus (1526-1586.)

She outlived her husband by 20 years, and resided in Wolkenstein Castle until she died at the age of 74.

Aside from giving birth to 6 children (without an epidural) her most interesting accomplishment was writing and publishing a book of etiquette for young ladies.
