Her age at burial in 1750 is stated as 69 years, which implies a birtth year of 1681. There are however, good reasons to believe that this age is off by ten years, and should be 59 years instead.
In the probate after her mother she is mentioned last of the children, after her sister Ragnhild who was born about 1689.
A birth year of 1681 also conflicts with the children of her mother's previous marriage, where the youngest was born about 1683.
Finally, her husband was apparently born about 1698. A birth year of 1691 at least puts them as born in the same decade.
