Mystery - Even Finnsen

Good evening, Can someone help me make sense of the story for my 6th great-grandfather, Even Finnsen? He was baptized on 17 Oct 1722. According to an author, he lived on Øveren in 1777, 1780 and 1801, but I never did I found a death or burial entry. These closest I found was below, but this was four years before the census. Even Finsen was a rare name in Buskerud County, I know none other, and the combination with the similar spelling of the Farm, makes me thing this is my Even Finnsen. But how would one explain the 1801 census then?
