Berit Aune Family

I am looking for the family of my great-great grandmother. She was the daughter of Johan Aune, but I don't know her mother's name. She was born August 3, 1850 probably in the stordal area of Norway. My main reason I want to find her family is to determine if she had siblings that had children. I wish I could provide more info to help in this search, but I only have this much. I should also mention that Berit was married to Torsten Lorntsen Julseth between 1879 and 1881.
