According to Topografiska kartan (which is now CC0 and available as a layer in JOSM) and http://www.bygdeband.se/plats/61274/sverige/vasternorrlands-lan/ornskoldsvik/anundsjo/stavro/ , it is Stavro, not Starvo. It seems to consist of at least two farms, so it would count as a hamlet in OSM terms. https://www.openstreetmap.org/user/PlaneMad/diary/34758
