Lisbeth is is eleven during Kirsten Learns a Lesson and twelve by Happy Birthday, Kirsten!; she has gray eyes and brown hair. She was born in Sweden and the family left when she was still a baby, so she has no memories of life there. Her father died years ago, and her mother Inger later remarried Olav. Lisbeth loves to talk, share secrets, and gossip, especially about supernatural or scary happenings. As the oldest, she has a little more experience than the other girls do about school, the wilderness, and responsibilities. She loved to tell scary tales about Mr. Coogan, their former teacher. She is very responsible and practical, but she likes to have fun as well. She helps Kirsten teaching her ways about America. However, as the oldest she can sometimes be bossy, too adult, and very demanding. She is very skilled at sewing and Kirsten thinks she can sew like an adult by the time she is twelve. Her favorite part of the Declaration of Independence is "Life, Liberty, and the Pursuit of Happiness..."
