She is known for her writing: she copied letters and documents from the Middle Ages, the originals of which have since been lost, and for her genealogical research.
She was born to riksråd baron Birger Nilsson Grip and Brita Joachimsdotter Brahe.
[1] In 1562, she married the noble Erik Månsson Natt och Dag, son of Måns Johansson and Barbro Eriksdotter.
After being widowed shortly after, she managed the estate Brokind Castle on behalf of her minor son Erik Eriksson Natt och Dag (d. 1566).
Genealogical research became common among the nobility in the late 16th century, but Grip are regarded as the pioneer of this genre in Sweden.
