Very little is known of Birchenbaum's life other than the account given in "En annan ny visa". Two other documents survive relating to Birchenbaum; they are petitions dating from the late 1660s, featuring her testimony that she was the widow of Major Axel Paulj Liljenfeldt, who died in the Thirty Years' War while serving in the Swedish army. Birchenbaum was a contemporary (though a younger one) of the Finnish poet Sigfridus Aronus Forsius.
