The location was actually in Ullensvang district of Hordaland, Norway (in the historical fjord area often known as Hardanger.) The farm names were Øvre Sekse and Midt Sekse but that couple later resided on the farm called Øvre Børve also along the same fjord and within the parish district of Ullensvang.
Odmund's (Aamund) parents were Torstein Jonson and Madli Knutsdtr. Anna's parents were Vigleik Askjelson and Ingebjørg Kristofersdtr.
The Ullensvang area is documented with parish church records as early as 1689 and at least two different published series of books showing the history and genealogy of the people who lived on the various farms there.https://familysearch.org/learn/wiki/en/Ullensvang,_Norwayhttps://familysearch.org/learn/wiki/en/Hardanger_og_Voss
