Anders Great Grandparents, Anders Olson Nilsebratan's parents were Ole Anderson Haravika, born circa 1751 in South Aurdal and Anne Hansdatter born circa 1738. Ole died in 1813 and Anne was still living in South Aurdal at that time.
Anders also had two half brothers(same Mother), Martin Jonsen and Gudbrand Gudbrandsen. Anders, Martin and Gudbrand(Gilbert) all imigrated to the United States and took the Lee and their sir name. I don't know if they came together or not or what year the came in, except that it was before 1877 because his first child was born in Minnesota in January of 1877.
