it would be quite difficult to find any information based upon the information given. Storsve is a place today in the Etnedal commune in the county of Oppland.
However, Etnedal was first establishet around 1894. Before that it could have been Bruflat Sokn but that is just a Guess. You can however try to look for this person in the Church book for this parish:
I see that you name this person Hans Mevensen which is a unusual name in Norway. Possibly his name was Hans (first) M (middel) Evensen (last from "son of Even").
