Rolvsøy
From Wikipedia, the free encyclopedia
Rolvsøy is an island and a former municipality in Østfold county, Norway.
It was created by a split from Tune on 1 January 1911. At that time Rolvsøy had a population of 2,381.
On 1 January 1994 Rolvsøy was incorporated into Fredrikstad, the neighboring municipality to the south. Prior to the merger Rolvsøy had a population of 5,947.
The Tune ship, a viking ship dating from ca. 900, was found in Rolvsøy in 1867. It was so named because Rolvsøy was a part of Tune at that time.
[edit] The name
The Norse form of the name was (probably) *Rolfsøy. The first element is then the genitive case of the male name Rolfr, the last element is øy f 'island'.
