Marit Olsdtr, 1801 cens Grotaasen farm Nordre Land

I have been having a hard time finding out where Peder Pedersen Grotaasen's second wife came from. I located Marit Olsdatter, born 1761, in the 1801 census on Digitalarkivet. However, there is no indication of which parish she was baptized in. I'm not sure that I know how to operate the options available for the 1801 census. Is there a button that will tell me where she was baptized or which farm she came from? really I have located four Marit Olesdatters that were born in Sondre Land in 1761 on the Mormon website at FamilySearch.org. However, that only gives parents' patronymics and no farm either. I wrote to the Statsarkivet and they had no luck trying to find out where Marit originally came from either. They did identify godparents for her oldest child's baptism: Joen Bierche, Niels Lien, and Taral and Guri Valhovd. My goal is to try to find: (1) her parents, and (2) her location in a bygdebok. Any help would be appreciated.
