Knut Syverson

Hey guys- Me and a few others are trying to figure out who Knut Syverson parents are. Our records show that he was born in Nord-Aurdal in 1756. Accord to this tree... Tree The parents are listed as Åbjør Syver Olson and Åbjør Berit Knutsdtr (chr Dec 25, 1756). While looking at the parish records for Aurdal, Oppland, Norway, we found another parish record that shows a Knud with Syver Knudsen and Ingebor Knudsdatter as the parents, chr December 29, 1756. Can you help me clear up the mystery on which record is the correct one? Also, The their was a couple that married October 4, 1787, names: Knud Syversen and Sigri Knudsdatter. They married in Vestre Slidre, Oppland, Norway. No parents are listed. We are wondering if this is our same Knud Syversen. Please help me on this one. Lucas
