Karin was born in August 1675, most likely in Nedre Ulleruds parish, Värmlands county.
On June 24, 1705, she was married in Nedre Ullerud to Olof Christophersson.
The following year, 1706, their first child was born, their daughter Ellika. By that time they were living on the farm Vartorp in Nedre Ulleruds parish.
When she became a widow, in September 1744, after the death of her husband, she still lived on the farm Vartorp in Nedre Ulleruds parish. After the death of her husband the farm was taken over by her daughter and son-in-law, Anna and Gustav Andersson.
Karin lived in Vartorp in Nedre Ulleruds parish for the rest of her life. Most likely she died in 1760. There are no church books for that year so no exact date is therefore known.
It is not known if she had any more children.
