Lars Halvorsen Aune (1689 -1761)

I am trying to verify some information on Lars Halvorsen Aune. I have that his son Halvor Larson (1718 - 1784) was born to Marit and to Guro Knudsdatter. It possible to have two wives but not two mothers. I have tried digitarkivet but can't come up with any info. I am also interested in the Aune farm that they lived on. Is there any pictures of the farm? Has any buildings survived from the 1700s? when did Lars Halvorsen Sr family moved to the Aune farm? I know it was sold in 1809 when the younger Lars Halvorsen Aune (1758 - 1840) sold it to his brother in law. Thanks in Advance.
