Hurdal Nordgaard family

Hello: My wife, who is a descendant of the Nordgaard family, and I, will be in Oslo later this month, We want to visit the Hurdal area and find out what we can about the family's origins. Is there a local history museum there, or a library that might have pictures, land ownership records, or local census information? What are the hours of service? Hurdal seems to be immediately north of the Gandermoen Airport. We hope there is bus or train service between the two, or from Oslo. Thanks for any assistance. Douglas & Karel Whitaker
