Gudrød Halvdansson «the Hunter» Veidekonge - Children older than himself.

Disconnected Rolf Gudrodsson - Gudrodsson means son of Gudrod, not Olaf.
As far as I know there is only one known child of Olaf: Ragnvald Heidumhære (Olavsson) (Rögnvaldur heiðumhæra), so the other should probably be disconnected as well. - Disconnected Jocunda Olafsdatter, N. Olafsson and Oystein Olavsson as well simply because they looked fabricated simply because only one person had added them and definitely looked as false genealogy without any source references.

In any case: None of the sagas mention any birth years, so they are fabricated by people of today and cannot be used as an argument to disconnect any lines. The sagas only tells who is son of who, and the mothers seldom named, unless royal or noble.

And none of it is provable so far back in time, so Ingrīda Cinkmane (Dzelvīte) your statements are not correct since they are impossible to prove.
