[3] sjöt Ynglinga ‘the residence of the Ynglingar’: The Ynglingar were the ancient ruling house of the Svíar, based in Old Uppsala, and celebrated in Þjóð YtI, which gives the names of twenty Swedish Ynglingar at Uppsala and six rulers over Norway. Legendary and historical sources claim that the Norwegian royal house that was dominant in the historical period descended from the Swedish dynasty. The pl. form Ynglingar appears only here in Old Norse poetry, although the sg. ynglingr ‘ruler, prince’ is more common; for a discussion, see Introduction to Þjóð YtI.
