In historischen Romanen und Erzählungen findet sich neuerdings die Darstellung, dass sie in Hirschfeld bei Nossen geboren worden sei, und dass ihre Eltern ein Hans von Bora zu Hirschfeld und eine Anna geborene von Haugwitz gewesen seien.[7] Beide sind historisch nicht nachweisbar.[8] Trotzdem wird der alte Taufstein aus der Hirschfelder Kirche, der heute im Kreuzgang des Freiberger Domes steht, mit ihr in Verbindung gebracht.[9]

Tatsächlich war Katharina wohl die Tochter des nur 1505 sicher belegten Jhan v. Bora auf Lippendorf und seiner ebenfalls nur 1505 erwähnten Ehefrau Margarete aus einer bislang unbekannten Familie (German Wikipedia)

Katharina von Bora, one of 12 nuns Martin Luther had helped escape from a convent two years earlier. Katharina was 26, Luther 41 years old. Ironically, the couple’s first home was a former monastery, a gift from John the Constant. They would have six children, four of whom lived to adulthood.

Katharina was an avid gardener, cattle breeder and competent Lady of the house and her and Martin led a happy life together. Many of Luther's circle of friends and supporters were dismayed by his marriage.

The Luther's lived in the Augustinian monastery, a bustling and happy home. They had many houseguests and boarders, including students and widows who would provide some much needed income, in addition to Luther's modest income, towards the running of the household.

Luther would sometimes jokingly refer to her as Lord Kate' because of her bossy and commandeering motherly ways, though no doubt it was necessary at times.

Luther's sisters' six children would live with them after her death.
