Interpret information on 1666 census please

I am researching my ancestor Ole Simensen. I only have his name from his daughter Anne Olsdatter (Rusnes) Who was born 1678 in Rusnes and died 1732 in Tolstad, Vågå, Oppland. This information comes from a 5th cousin. Recently while searching the 1666 I came upon an Ole Simensøn, (# 3200), age 16 years. Correct farm and correct age to have had a daughter born in 1678. He does not seem to be living with his parents although his status is Sønner. What is his relationship to Torkel Erlandsøn? Can someone explain to me the information given on this census record? Thank you so much. Marlon Henvit Reno, Nevada USA
