Translation help needed

Here is a passage from the Åmli bygdebok. Could someone take a look at my rough translation and see if any corrections are needed. Much appreciated. Bygdebok passage. Lars Ånonson og Gunhild fekk i 1837 festbrev på plassen Støylsjordet som var avgrensa med byttestein. Med plassen var snaut rydda frå for. Til plassen skulle høyre 30 slåttestyker og fiskevatnet Dybedalstjernet, og Lars kunne sette garn i åna. Husbonde skulle halde hjuring for 2 kyr og 16 småfe. Årleg leige skulle vere 6 veker slåtterarbeid. Lars kom til bygda i 1816 frå Bråstad i Øyestad, men var nok frå Haukom i Vegusdal. Gunhild var truleg au frå Vegusdal. Det var visstnok i Vegusdal dei vigde, og sume av borna er fodd der. Vi veit om 5 borna dei. My rough translation Lars Ånonson and Gunhild received a written contract for the lease of land in 1837 on the husmansplas Støylsjordet, which was bounded by stones. The space was barely cleared. To the right of the place was 30 mowing pieces and the fishing lake Dybedalstjernet, and Lars could put nets in the river. The head of the household could keep herding for 2 cows and 16 sheep. Annual rent should be 6 weeks mowing. Lars came to the village in 1816 from Bråstad in Øyestad, but was probably from Haukom in Vegusdal. Gunhild was probably also from Vegusdal. It was probably in Vegusdal that some of the children were born We know about 5 of them.
