Thank you so much for your help. Yes, you have the census and marriage right. A couple of days ago, I found this record which I'm pretty sure is his burial record. The description uses the name of the same child, Hans Laursen, as the burial record I found for Margrethe Hansdatter. He is their oldest child and oldest son.
Danish State Archives, Church Counter Books, database with images, Voer Parish (Hjørring County), Enesteministerialbog (1687 - 1814), 1717 FKVD - 1806 FKVD, image 119 of 187, folio 117, middle of left side, Burial of Laurs Pedersson (https://www.sa.dk/ao-soegesider/da/billedviser?epid=17128204#172545,28969157 - death date: 1 May 1802, Hans Laursen's father, Laurs Pedersen, age 76, buried the 3rd Tuesday after Paske (4 May 1802)
This age of 76 would put his birth around 1726 which is still a couple of years off from the census but much closer in age than this baptismal record.
We also have a spread dates on the 4th great grandmother's birth. The 1801 census puts her birth around 1734. The 1787 census puts it around 1737. Her burial record fits better with the 1801 census. If the first record I asked about is her baptismal record, it would put her birth in 1736 which is close to the 1787 census age. Can you help any with that?
