Ingerid Gudvangen Stigen

I wish to learn more about the family in which my great-grandmother Ingerid Gudvangen Stigen was born and raised. The location was Aurland parish, Sogn og Fjordane. Ingerid was born in March 1824, and I believe emigrated in 1849, possibly accompanied by a sister Ingeborg, and perhaps other siblings. Names of her parents and siblings, plus other pertinent information if readily accessible will be appreciated.
